The boy asked his mother go out to relax himself or not.

A. whether could he

B. if he could

C. that he could

D. whether he could

答案：

A. whether could he

B. if he could

C. that he could

(答案→)D. whether he could

解析：考查宾语从句，句意：这个男孩问他的母亲是否他可以出去放松自己还是不可以。根据语义应用连接词whether/if, if不能与or not连用，因此用whether,语序应用陈述句语序，所以选D。
