Short paragraphs, un varied punctuation, the redundant use of the subjects name
I am not 100% sure, although I feel the best answer to this question is A. The poet is saying that people don't live long; life is short.
This is because he talks about someone remaining, or living on. You can infer from this that the poet believes that life feels short and brief. The poet doesn't mention beauty in this line, nor foes he express changes in his generation. However, D is still a possible answer, but he doesn't focus as much on himself and his unwant to grow old. I hope that this can help you out! :D
A structual element for a poem would be stanzas. Hope this helped you a bit.
