问题补充：

—Mum, may I go out to play football for a while?

—. You need some exercise.

A. Never mind

B. You’ve got it

C. Go ahead

D. It’s your turn

答案：

A. Never mind

B. You’ve got it

(答案→)C. Go ahead

D. It’s your turn

解析：考查交际用语。Never mind没关系，别介意；You’ve got it你明白了；Go ahead去吧；It’s your turn该你了，轮到你了。根据You need some exercise.，可知答应了上文的请求，所以选C。
