Answer:
A) he wishes to see narrator because he is ill.
Explanation:
Roderick Usher summons the narrator because he is very ill and believes that he will die soon. However, even though this much is clear, it is not clear what Roderick expects the narrator to do about it. Moreover, the narrator and Roderick are not close friends. Instead, they were friends in childhood but have grown apart now. This is evidence of how lonely and isolated Roderick is.
