15. Parents love their children with a devotion _______ no return.
A. which they ask for B. which they ask
C. for which they ask for D. for which they ask

为什么选C，不是D。
请高手分析一下。谢谢
那里面两个for分别是什么作用啊
最好能有例句，谢谢。

从句改成正常句式相当于
ask for no return for which
no return 是ask for的对象，第二个for做“由于”讲
因为which，她们ask for no return

正常语序是they ask for no return for devotion

所以是c，又两个for

C. for which they ask for
ask for sth for （no)return.不求回报的爱

后者是词组ask for 表要求 ask for no return 不要求回报
前者则表示原因
