Answer:
B). It can help narrow your topic.
Explanation:
A problem-and-solution essay is demonstrated as an essay that identifies or unveils a problem associated with a situation and develops to propose direct solutions to the given problem which is often followed by an evaluation and conclusion that intends to substantiate the validity and efficacy of the solution for the problem. A 'topic web' is quite effective to design the ideas or structures of such essays as they help present and develop the ideas more effectively.
As per the question, 'topic web' would assist in 'narrowing the topic' and specify the problem(or problems) that is going to be addressed and put solutions for in the problem-and-solution essay. It would help frame the idea of the essay and evaluate the different problems and its possible solutions(and remove the unnecessary content) in a single frame more clearly and impactfully. Thus, option C is the correct answer.
