---Can you come to my party on Saturday afternoon?

---.I’ll have to help my parents.

A. Sorry, I can’t.

B. Yes, I’d love to.

C. Let’s go.

D. No, I don’t think so.

答案：

(答案→)A. Sorry, I can’t.

B. Yes, I’d love to.

C. Let’s go.

D. No, I don’t think so.

解析：根据I’ll have to help my parents可知，不能去，故排除BC；而D的意思是“不，我认为不是这样的。”不符合题意。所以本题选A。
