Answer:
C. The poet is relying on visible images to make an important point about the setting
Step-by-step explanation:
From the statement, the poet is relying on visible images to make an important point about the setting: which means that the experience was not a pastoral vision of the ideal, as it at first seemed; but nor did it end in death, but rather the poet is fully awake.
Furthermore, this means, the poet has overcome the numbness of the senses, and the dullness of the mind, which is associated with dreams. Hence, he can see and hear, and need not guess. The body is thinking, not dreaming.
