For adolescents, risk of drug abuse increases greatly during times of ________.

A. Transition
B. Divorce
C. Changing schools
D. Both A and C

B?

I disagree.

It was D

D was the answer.

The answer to the question is D. Both A and C. During times of transition and changing schools, adolescents often experience increased stress, pressure, and a sense of insecurity. These factors can contribute to an increased risk of drug abuse. To arrive at this answer, we can eliminate option B, "Divorce," as it is not mentioned in the question. Then, we can analyze the remaining options A and C. Both transitioning and changing schools involve major life changes and can have a significant impact on adolescents. By combining these scenarios, the risk of drug abuse for adolescents increases greatly. Therefore, the correct answer is D. Both A and C.
