Is this the reason in the report for her success in the job ?

A. she explained

B. what she explained

C. how she explained

D. why she explained

答案：

(答案→)A. she explained

B. what she explained

C. how she explained

D. why she explained

解析：考查定语从句。She explain是定语从句修饰the reason;she前面省略了that/which.句意：这就是在报告中她解释的工作成功的原因吗？
