Poems are not like diaries, even if they are written in the first person. This means that the "I" in a poem is not the voice of the poet, but rather is the voice of a whole other character, the speaker (who is equivalent to the narrator of a novel). Each poem will have its own distinct speaker, which accounts for the different views of spring in this question.
The correct option is B. Looking at the two passages given above, it will be observed that the opinions given about springs and cattle in the two excerpt differ; this shows that those views are been expressed by two different personalities. The first passage talks about a man, who hate to put up a wall, since he has no cattle. He believes that walls are only needed when one has cattle, the walls prevent the cattle from disturbing neighbors. The other man on the other hand has cattle.
