The answer to your question would be that suspense is created in the passage partly due to it being written in the third person limited point of view. That is, your answer would be C.
In the third person limited point of view, the narrator follows the thoughts and feelings of only one character. One character is closely followed throughout the story, and it is typically the main character. In this case, the narrator only follows Rainsford, someone else is seeing and narrating how he feels and that is what builds up the suspense.
Answer:
"Under the astonished, wide-eyed moon, with the fires casting strange shadows upon these towering figures, I am rather inclined to believe him."
Explanation:
The use of the words "astonished" and "wide-eyed" that are used to describe the non-human presence of the moon creates a feeling of wonder. It depicts a scene in which the moon is large (wide-eyed) and beautiful (astonished). This and the description of the fires and their shadows creates an almost magical scenario to help the reader envision what the narrator is seeing. The personification aids in this, allowing us to understand how the narrator <em>feels</em> as well (wonder).
The words "casting upon" can also be considered personification, but it is not relevant in this case.
Lord and Lady Capulet both have strong emotional reactions to Juliet's refusal to marry Parris. When Juliet gives her answer, Lord Capulet gives her an ultimatum: marry Parris or he'll disown her. Lord Capulet does not have a rational conversation or hear Juliet's concerns. Lady Capulet also reacts emotionally when she refuses to listen to her daughter as well.
They are called "Tercet".
