(单选题)

—Tony is talking with our English teacher over there, isn’t he?
—No, it ______ be him. He is absent from school today.

A.won’t

B.mustn’t

C.can’t

D.needn’t

参考答案：C

参考解析：

考查情态动词表推测。句意：“Tony在和我们的英语老师在那边谈话，是吗？”“不，不可能是他。他今天没来上学”。won’t意为“不会”；mustn’t意为“禁止”；can’t意为“不可能”；needn’t意为“不需要，没必要”。根据句意可知，此处应表示否定推测，can’t be意为“不可能”。故选C。
