D. when they're most comfortable with and have a clear understanding of who they are.

Explanation:

Adolescence is a transitional phase between childhood and adulthood. This is a time when the discernment of the person grows steadily, so that the person can better understand the workings of daily life, the responsibilities of each person and their own identity. This is a maturing process. The consensus of scientists is that this transitory phase may be different for each person and what defines the end of adolescence is the complete development of the brain, when the person will have the proper discernment for life situations. There is no specific age, but today scientists say it can happen up to 24 years.
