I believe the correct answer is D) Tom was aware of Jim’s attachment to Betty.
In the last scene of the play “The Glass Menagerie” written by an American playwright Tennessee Williams, Amanda thinks that Tom was aware that Jim was engaged to Betty after she hears the news about Jim’s engagement. She confronts Tom and after that she realizes that she made a mistake because even Jim says Tom didn't know that he was engaged, but she can’t take it back.
