Quizplus · Accepted Answer

The collision-coalescence process occurs in warm clouds with temperatures above freezing. Option A, C, D and E are all thick clouds with cold temperatures where the Bergeron process is dominant. Option B is a thick, warm cloud where the collision-coalescence process is the only way precipitation is formed.
