Answer:
The apostrophe in a poem is a figure of speech where the speaker addresses someone or something that is not present or cannot respond. To convey this effectively, a performer could use body language and tone of voice to create a sense of addressing the absent person or thing.
Out of the options given, the action that would best convey the apostrophe in the poem is:
C. Closing his or her eyes.
Closing the eyes can give the impression that the performer is addressing someone or something that is not present, as if they are imagining the recipient of their words. This action could be paired with a change in tone of voice or facial expression to emphasize the apostrophe and create a more powerful emotional effect on the audience.
