A)The narrator feels that no one has ever experienced a love like theirs, even though they were children. He says that no one older or wiser has ever loved like they did. Â
D)He provides clear details about how she died. It shows that he understands her illness was natural.
these two are my top choices but i think it is D because it states he understands her illness was natural. A we are not sure if somone else love more then him/her
