I believe the answer is: c. rapturous / grieving
the poet in the wanderer told the experience that felt by someone who is on an exile.
In the poem, the poet reminiscence the better times before he is on exile and what he might do when he manage to come out from it. The grief on that dream come because he realize that the dreams would most likely never be realized.
The answer is E
A, B, and D are singular instead of plural.
C is repeating the same words from the beginning of the statement which creates unneccessary repetitiveness.
