Answer:
D. She is spending more time with her peer group than she spends with her family
Explanation:
While the 'recent identity crisis' is most likely the biggest overall change, this question deals with changes in her social life, or the people she talks to. Many will look at social life as merely friend or peer groups but in some cases parents, cousins, and siblings can also be friends and peers.
Therefore, the change in her SOCIAL life is best demonstrated through her shifting time spent with her family to time spent with her friends and peers.
