Answer:
Option: B
Step-by-step explanation:
The rhetorical device employed in these lines is metaphor. The author uses metaphorical language to describe the experience of America. The line "Although she feeds me bread of bitterness" metaphorically compares America to someone providing nourishment that is bitter or unpleasant. The phrase "sinks into my throat her tiger's tooth" uses metaphor to portray America as something fierce and painful. Therefore, option B, metaphor, is the correct answer.
