A solution is a type of homogeneous mixture that is made up of two or more substances. A homogeneous mixture is a type of mixture with a uniform composition. This means that the substances cannot be distinguished easily from one another.The two components are well mixed that we can not see the individual components separating out.

Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture.

Hint: A solution is a homogeneous mixture of two or more substances which consists of one phase. Homogeneity is something that is evenly distributed. Complete step by step solution:
It is also the mixture of solute and solvent. Solute is the substance being solved. Solvent is the substance in which the solute is dissolved. If all the particles in the solution are in the same phase, then it is called homogeneous solution. For example, air is a mixture of different types of gases like oxygen, nitrogen, etc.
A. Milk is visibly a homogeneous mixture, but when observed under a microscope, it has tiny particles of fats and proteins. Thus it is not a solution. Colloidal solutions are the solutions in which one substance is suspended over another.
B. Smoke is a colloidal mixture of solid particles in liquid or gas. Thus it is called a solid aerosol in which the dispersed phase is solid and the dispersion medium is gas. Some examples are mist, dust, fog etc.
C. Brass is an alloy of copper and zinc. Metals or metals with nonmetals mixed homogeneously are called alloys. Therefore this is an example of a solution. This is a solution of two solids. Percentage composition of copper in brass is $70\% $and that of zinc is \[30\% \].
D. Face cream is an example of emulsion. Emulsion is a colloidal solution in which dispersing medium and dispersed phase are liquid.Therefore, Option C) is the correct answer.

Additional information:
A solution need not be in the liquid phase. It can be of two solid mixtures also. But both should be in the same phase.

Note:
Smoke, face cream, milk are examples of colloidal solutions. Colloids are classified on the basis of their dispersing medium and dispersed phase. They are liquid aerosol, solid aerosol, foam, emulsion, sol, solid foam, gel, solid sol.

Hint:In a solution, a substance known as a solute is dissolved in another substance known as a solvent. For example, when sugar is dissolved in water, it forms a solution. Here, sugar is the solute and water is the solvent.

Complete step by step answer:
- In chemistry, a solution can be defined as a homogeneous mixture of two or more substances.
- The amounts of these substances can be varied continuously up to the limit of solubility.
- In a solution, the particle size of the components is about 1 nm.
- Some common examples of solutions are salt, or sugar in water, soda water, etc.
- All the components in a solution are in the same phase.
- The particles in a solution are evenly distributed or it can be said that the solution has particle homogeneity. And due to this reason, samples taken from the solution will have the same properties and constitution of the components as that of the main solution.
- A solution has two components: a solvent and a solute.
- A solvent is a component that dissolves the other component.
- A solute is a component that is dissolved in the solvent.
- In general, we can say that the solvent is the major proportion of the solution. Or, in simple terms, the amount of solute in the solution is less than that of the solvent.
- For example, the air is a homogeneous mixture of gases in which both the solvent and the solute are gases.

Therefore, we can say that a solution defines a homogeneous mixture of two or more substances. Hence, option (A) is the correct option.

Note: There is a difference between a mixture and a solution. Mixtures can be heterogeneous as well as homogeneous. Whereas, a solution can only be homogeneous in nature.

Is an solution a homogeneous mixture?

Solution: a homogeneous mixture of two or more substances. Example: water, sugar, flavor mixture (Coke). The substances are physically combined, not chemically combined or bonded to each other.

Is solution always homogeneous?

A solution is always a homogeneous mixture. A solution is always a homogeneous mixture. The solute particles in a solution have size less than 10 A. Brass connot be called a solution.An ionic compound dissolves in water if the hydration energy is greater than lattice energy.

How do solutions become homogeneous?

Homogeneous mixtures can be solid, liquid or gas, but in order to be homogeneous, or form a solution, they must be of uniform state once mixed. Homogeneous mixture can be formed in many ways. Sometimes a gas can dissolve in a liquid like in a carbonated drink where carbon dioxide is dissolved in water.
