Answer: B. Both are made up of two substances that are not chemically combined
Explanation:
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present.
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different.There is a physical boundary between the dispersed phase and dispersion medium.
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different.There is no physical boundary between the dispersed phase and dispersion medium.
Solution is a mixture made up of solute and solvent which do not combine chemically. They can be homogeneous or heterogeneous.
Thus a solution be classified as a mixture as both are made up of two substances that are not chemically combined
