问题补充：

----- Must I park my car behind the building?

------No, you . You park it here .

A. mustn’t ; may

B. may not ; must

C. don’t have to ; may

D. shouldn’t ; must

答案：

A. mustn’t ; may

B. may not ; must

(答案→)C. don’t have to ; may

D. shouldn’t ; must

解析：must的回答方式的肯定回答用must，否定回答用needn’t或don’t have to，不能用mustn’t，因为其表示禁止做。本句的意思应该是“不，你不必。你可以停在这儿。”所以本题选C。
