Answer:
D. It depicts the Vietnam War as a stone that heavily weighs on the speaker's conscience.
Step-by-step explanation:
According to the lines from the poem Facing It by Yusef Komunyaka, the author talks about trauma and how when he turns one way the "stone let's him go" and if he turns the other way, he's back in Vietnam. This suggests that the poet is talking about a war veteran from the Vietnam war.
The sentence that best describes one effect of the poet's use of figurative language in the excerpt is option D which depicts the Vietnam War as a stone that heavily weighs on the speaker's conscience.
