C
A homogeneous mixture
D

Verified step by step guidance1
Understand the definition of a solution in general chemistry: a solution is a mixture where the composition is uniform throughout.
Recall that mixtures can be classified as either heterogeneous or homogeneous. A heterogeneous mixture has visibly different parts, while a homogeneous mixture appears uniform.
Recognize that a solution is a type of homogeneous mixture because the solute particles are evenly distributed within the solvent, making the mixture consistent in composition.
Note that a solution is not a pure substance, as it contains more than one component, but it behaves as a single phase with no visible boundaries between components.
Understand that solutions can involve any phase combinations (solid, liquid, gas), so they do not always contain a solid solute and liquid solvent; this is just one common example.
