Answer:
D.
Explanation:
A conditional mood is a request or in condition of something happening in the future; it uses auxiliary verbs.
It is not A because it is a demand and a statement.
It is not B becaus it is a demand.
It is not C because C is in condition of something that has <u>already</u> happened in the past.
It is D because it is a request.
This suggests a possibilty, whether it is through a request (requests can be denied or accepted) or scenario in which things are suggested to alter the future, even if it can't be changed.
This question is based on "Pride and Prejudice", a novel that was written by Jane Austen. The reason why Mr. Wickham wanted to get Miss Darcy to marry him is that he wants to make Lydia jealous. The answer for this would be option C. Hope this helps.
