I believe it’s letter “D” sorry if u do get it wrong
I don't like the way this is worded. An allegory is a short type of poem. Not a genre. But the answer is D. If you look at general poetry structure, it tells a vivid story in a confined manner.
Well, it's not A. Mary did not let hm accept the disease.
It's not B-he told her about his mother (I think).
It's not D because she is brought to live there.
It's C because she doesn't let him accept his illness and ends up helping him.
Your teacher will for a fact i know that so dont use it twice
