she could not decide_____________ A.she chose which one B.to choose which oneC.that which one she chose D.which one to choose答案是D为什么
答案 D 是正确的.
这里是【 疑问词+动词不定式 】的固定结构.
意思是：她不能决定该选哪一个.

这是带疑问词的不定式 作宾语 疑问词which one 是不定式的宾语
必须提前 ，只有这样 才相当于一个宾语从句= which one she should choose.

decide to do sth

D.是定语从句啊！！因为which one 提前了。
