• C. Colloid
• D. Homogeneous mixture

Answer: (D)

Verified step by step guidance

1. Understand the definition of a solution: a solution is a mixture where the components are uniformly distributed at the molecular or ionic level, resulting in a single phase.
2. Recall the types of mixtures: heterogeneous mixtures have visibly different parts or phases, colloids have particles dispersed but not dissolved, and suspensions have larger particles that settle over time.
3. Recognize that a solution does not have visible particles or phases and appears uniform throughout, which matches the characteristics of a homogeneous mixture.
4. Compare the options: suspension and colloid are types of heterogeneous mixtures, so they do not describe a solution.
5. Conclude that the best description for a solution is a homogeneous mixture because it is uniform and consistent in composition throughout.
