Answer: The right answer is the B) A ward of Mr. Rochester.
Explanation: Just to elaborate a little on the answer, it can also be added that the solitary and spoiled character of Adèle Varens is Jane's student at Thornfield Hall. She was born in France and was brought by Mr. Rochester after her mother (one of Mr. Rochester's mistresses) abandoned her. Although Mr. Rochester does not think that she is his daughter, he eventually adopts her.
