The answer is C: luster.

Explanation for each option: A. Specific gravity - This refers to the density of a mineral compared to the density of water. It is not related to how a rock reflects light. B. Cleavage - This describes how a mineral breaks along certain planes of weakness in its structure. It does not pertain to the reflection of light. C. Luster - This is the correct answer. Luster describes the way a rock or mineral reflects light from its surface, such as being shiny, dull, metallic, or glassy. D. Streak - This refers to the color of the powder left behind when a mineral is scratched against a porcelain plate. It is not related to light reflection.
