Hello there!
The question appears to asking about what represents the poem's subject.
First, we can imply what our general topic by the thesis. The thesis is usually the first sentence in a story, and is restated in the conclusion.
The first sentence is "I wandered lonely as a cloud." and the rest of the story details the poem's thesis.

Your answer is A.) Cloud.
