Final answer:
The figurative language used in the excerpt is metaphor, comparing the daughter's desire for fashion conformity to being a slave, and the lingering impact of past anguish to spectral entities. Option A is correct.
Step-by-step explanation:
The figurative language used in the excerpt from Barbara Kingsolver's "Life Without Go-Go Boots" is metaphor. A metaphor is a figure of speech that compares two unlike things without using the words "like" or "as." In this excerpt, the author compares her daughter's desire to conform to conventional fashion with being a slave, emphasizing her own resistance to such conformity. The line "Always and forever, the ghosts of past anguish compel us to live through our children" is another metaphor, comparing the lingering impact of past anguish to spectral entities that influence our actions.
