The correct answer choice to the question: According to the theory of aging, Bea is aging successfully, would be, A: Activity theory of aging.

Explanation:

The Activity theory of Aging, also known as the activity theory establishes that  in order for a person to face the process of aging in a positive manner, and ensure a good quality of life, he, or she, must maintain a certain level of activity and social engagement with the environment in order to achieve this. The opposite theory would be the Disengagement theory, and the activity theory proposes, unlike the first one, that it is in this social involvement and activity maintenance that people are able to go through the process of aging and be happy. This theory was developed in 1961 by Robert J. Havinghurst.
