C would define it the best I hope this helps you
The question is asking to state the correct trait or stanza pattern to the excerpt that uses it, I would say that the answer would be that it is written in alliterative verse. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications
Answer:
A prepositional phrase is a modifying phrase which includes a preposition (in this case, "over") and the object of the preposition (in this case, "the mantelpiece.")
The theme highlighted in the mentioned excerpt would be perseverance.
The excerpt tells of Rainsford's courageous act of braving the sea to go to the direction of the shots despite of the harsh conditions at the sea. This is evidenced by the phrase "he fought the sea".
The term "doggedly" also describes a persistent pursuit which was what Rainsford showed. He showed perseverance in his actions.
