Answer:
B.
Step-by-step explanation:
the clarity of the thesis statement would be the most effective area to revise if you want to improve the overall focus of a close analysis of a poem.The thesis statement is the main argument or claim that the analysis is based on, and it should clearly and specifically state the focus of the analysis. By revising and improving the clarity of the thesis statement, you can ensure that your analysis is focused on a specific aspect of the poem and avoid including irrelevant or tangential information.While supportive evidence and sentence structures are important aspects of a close analysis, they are secondary to the thesis statement in terms of establishing a clear and focused analysis.
