I have read this poem, and there are many themes. However, in this one particular excerpt it seems like the answer being sought is C. A moment lost in time does not return. I say C because the final line states that the "tender grace of a day that is dead will never come back to me." Therefore, for this one particular part of the poem, we can see that the speaker does not feel like life is endless, there is no mention of the meaning of life, and there is no real mention of progress being made. The only things he talks about are wishing he could reverse time and have "the touch of a vanish'd hand, and the sound of a voice that is still!"
I really hope this is correct and helps you :) Good luck!
