The correct answer is B. Meter does not influence the setting of a poem.
Meter influences meaning, rhythm, and pace. Meter influences these elements because it is a pattern of beats. As a result, meter directly affects rhythm and pace. Meter can also influence the meaning of the poem, because meter can control whether the poem sounds happy or sad.
Meter does not, however, influence the setting. The poet conveys the setting through word choice and imagery, both of which are separate from meter.
