Câu hỏi: He must have canceled his e-mail account. I can’t get hold of him.

A Since I’m unable to get in contact with him, it seems certain that he’s closed his e-mail account.

B If no one is able to get in contact with him, he ought to get an e-mail account for himself.

C I must have got his e-mail address wrong, because he’s not giving me any reply.

D He may have closed his e-mail account, but I won’t know for sure until I get in touch with him.
