--- Will you please spare me a few minutes now?

--- , but I’ll be free in half an hour.

A. No, I can’t

B. Yes, with pleasure

C. No problem

D. I’m afraid not

答案：

A. No, I can’t

B. Yes, with pleasure

C. No problem

(答案→)D. I’m afraid not

解析：句意：--你现在能腾出几分钟给我吗？,但是我半小时后有空。说明是委婉拒绝了，I’m afraid not恐怕不能，A. No, I can’t不，我不能（不够礼貌），B. Yes, with pleasure 是，很乐意，C. No problem没问题，都和句意不符，选D。
