Is this ?

A. you are looking for

B. that you are looking for

C. what are you looking for

D. what you are looking for

答案：

A. you are looking for

B. that you are looking for

C. what are you looking for

(答案→)D. what you are looking for

解析：考查名词性从句。句意“这就是你要找的东西吗？”从句中的looking for缺少宾语，故用what，排除A、B；表语从句应该用陈述句语序，排除C。故选D。
