问题补充：

With your help, there is no doubt our plan is meant for will work out successfully.

A. that what

B. whether that

C. what that

D. that whether

答案：

(答案→)A. that what

B. whether that

C. what that

D. that whether

解析：考查从句。there is no doubt后面的整个句子是doubt的同位语从句，doubt用在否定句中，同位语从句用that引导；排除B,C； our plan is meant for是主语从句，且从句缺少for的宾语，所以用what引导。选A。
