Cynthia is active in the school band and student government, and she has a good group of friends. she typically does well in her classes, but she is struggling with her biology class. she goes in to talk to her teacher, and he offers her some makeup work, but cynthia has doubts. she does not feel like she is smart enough to pass the course. what could be interfering with cynthia’s decision-making process? too many friends low intelligence too many activities low self-esteem

D.) Low Self-Esteem

Explanation:

Cynthia's back story does not provide any evidence to support that she has too many friends or that she is in too many activities.  It explains that she does well in all of her other classes besides Biology, so it is safe to say her lack of confidence is not caused by low intelligence.  

So finally, with all of the above in mind, I am lead to the answer being Low Self-esteem.  She does not think she is smart enough to pass her course because she is not confident in herself.  

Confidence is key!

Low self-esteem

This is a common way to say that you aren't smart enough to pass a test and don't have confidence.
