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 biological parent is a parent that one comes from, they are your real parent. An adoptive parent is a parent is a parent that actually takes you from the biological parent because the biological parent wasnt fit to keep you; they are now your parent. Now a foster parent is in between a biological parent and an adoptive parent because they are your guardian for a time but they can give you up at anytime to another person, they are practically like a babysitter until you become adopted. An adoptive parent has to keep you whether they want to or not unless they cant provide for you any longer.
