Answer:
This is an example of b. misjudging other people's abilities.
Step-by-step explanation:
There is no information in the problem that Laura failed to take responsibility for her mistakes. It simply states that she made several mistakes. Because Rita showed Laura how to remember each step, we can assume that she listened to her. There is no other information about Rita trying to talk about the work. In fact, one of the assumptions is that she was not smart because she did not say much. The option D does not apply in this case. It is about Laura's attitude towards Rita and a misconception associated to the fact that Rita did not speak much. Thus, b. is the correct answer.
