The most accurate response based on the context of Jane's feelings and motivations is:
A) Jane makes it clear she does not love Clayton but cares for him and therefore does not want to leave him brokenhearted for the rest of his life with a loveless spouse.
This response highlights Jane's recognition of her lack of romantic love for Clayton, which influences her decision, whereas options B, C, and D emphasize preference or practical considerations without capturing her emotional motivations.
