（）—Mary can't help___the house,why?
--Because she is busy___a hotel reservation.
选择 A:to clean,making
B:cleaning, making
C:cleaning,to make
D:to clean, to make.

答案选 A

首先是can't help的用法，
can't help to do sth 帮不上忙做某事

can't help doing sth 忍不住做某事

所以先确定答案在A 和 D中选。。。

其次是 be busy doing忙于做某事。。。

所以确定答案为A

a

can't help doing sth.和be busy doing sth.是固定搭配
