Which statement best describes how this plot event shapes Claudius?

A. Laertes's arrival renders Claudius remorseful and contrite.

B. Laertes's popular support increases Claudius's insecurities.

C. Laertes's chaotic entrance makes Claudius become violent.

D. Laertes's demands prompt Claudius to change his politics.

I believe the correct answer is B. Laertes’s popular support increases Claudius’s insecurities.

People in Denmark love Laertes, and now they are especially feeling for him given that he has lost both his father and his sister in a short period of time. This is why they support him, which is not something Claudius likes and wants to get rid of both Laertes and Hamlet.
