Question

How do the words grieving, sigh, and blight affect the mood of "Spring and Fall"?

Answer 1

The most possible answer is either D or A. 

In both cases, it's quite sure that these words "grieving, sigh, blight" all represent a more sorrow deviation or a more deepened mood. The best answer of the two would probably depend on how you view the poem, either as one with a hopeful mood or one with a sorrowful mood.
