2 points

Explanation:

A solution is a homogeneous mixture. It can be colored (e.g., copper sulfate solution is blue) but must be clear (no suspended particles that scatter light significantly). A colloid has particles that are larger than in a solution but smaller than in a suspension and can be colored or colorless. The key here is that the first blank is about a solution's property (can be colored but clear) and the second blank is about a colloid (which can be colorless).

Answer:

B. colorless, clear; C. colloid, colorless
