The correct answer is B. It emphasizes the conflicts surrounding integration.
Explanation:
A simile occurs when a situation, person or idea is described using a comparison. Additionally, in simile words such as like or as are used to establish this comparison. In the case of the text presented, there is a simile in "buses lined up like tanks on a battlefield" because the author compares the arrangement of the buses to the tanks of a battlefield.
Moreover, this idea conveys a deep meaning because in this context (May of 1974) the integration program began and this led to multiple conflicts between black and white students "A police officer keeps the peace as black students board the buses". Therefore, by comparing the buses to the tanks the author can show the importance of the conflicts that occur as a result of integration (Option B).
