Carla, a Sixteen Year-Old Girl, Has Begun Spending More and More

Carla, a sixteen year-old girl, has begun spending more and more time with her friends. Her mother is quite happy that she seems to be forming some intimate, close friendships, but worries Carla's friends have too strong of an influence on her. It seems Carla now dresses according to what her friends think is acceptable, not what her mother does. According to research, Carla's mother should:

A) not worry, because Carla is bright and she will eventually find different friends
B) worry, that if she no longer influences Carla's small decisions, she will no longer have influence on the larger, more important decisions
C) not worry, because in the important decisions such as career choices, religion, and morality, parental influence remains high
D) worry, as she no longer has any influence over important decisions in Carla's life
