Answer

Brief Explanations:

In igneous rocks like granite, crystal - size is determined by cooling rate. Slow cooling allows atoms to arrange into larger crystals, while fast cooling results in smaller crystals or even glassy textures. The other options (sample size, number of times minerals were in granite before, and number of impurities) do not directly determine crystal size.

Answer:

D. how quickly the rock cooled
