Answer:
B. she'll live on in his poem.
Step-by-step explanation:
Shakespeare wrote sonnet 18, and in this sonnet he is speaking about his love for a woman, and how she was beautiful, and how he loved her, in his final lines he expresses:
"When in eternal lines to Time thou grow'st.
So long as men can breathe, or eyes can see,
So long lives this, and this gives life to thee."
So in this lines Shakespeare expresses that she will live on forever in the lines of his poems, as long as the poem lives, the lines on the poem would give life to her memory.
