Answer:
A. It emphasizes a feeling of excitement.
Step-by-step explanation:
In this stanza of the poem, Toboggan was used repeatedly to emphasize excitement. The poet described their descent from the hills which he compared to a comet that whizzes along the sky. He explains that the feeling was a grand one.
As he grasped the best winter girl by the hand, probably through their descent the poet used the exclamation, Toboggan! Toboggan! Toboggan! This is a feeling of excitement.
