The answer to this question is C, Gretchen’s reasons for her beliefs. The other answers don’t apply for the following reasons: even if her parents were restrictive, her having different ideas from them doesn’t mean she’s rebelling. Even if she’s been bullied, that doesn’t mean she’s rebelling against her parents either. Whether or not she’s studied political science in school is also irrelevant, because plenty of people form educated opinions in politics without going to school. To determine whether she’s rebelling or has a healthy sense of her identity, you’d need to know the reasoning behind her beliefs. If she has genuine answers as to why she feels a certain way, she’s likely got a healthy sense of her identity and has simply developed her own opinions.
