问题补充：

There’re too many clothes in the shop. I really can’t decide .

A. which to buy coat

B. to buy which coat

C. which coat should I buy

D. which coat to buy

答案：

A. which to buy coat

B. to buy which coat

C. which coat should I buy

(答案→)D. which coat to buy

解析：题干中的第二句话可以是简单也可以是复合句（宾语从句）。A选项中coat应该放在which之后，表示哪件衣服；B选项中which作为特殊疑问词应放开头；如果选C，就是宾语从句，应该用陈述句语序，should的位置不正确。所以本题选D。
