It would actually be B. Heroic Couplet. A heroic couplet is written in iambic pentameter (pretty much meaning 10 syllables per line), the last word of each line in the couplet (2 lines) rhyme with each other, and the whole couplet completes a thought. The first 2 line of this poem meet all of these requirements.
It could be both heroic couplet or personification, but I promise you it is Heroic Couplet, because if you are looking at this question for answers, if you go back to you lesson page 2 it talks about the traits of a heroic couplet. They want you to be able to recognize them and they assume that you can already recognize personification.
Hope this helps!
