A)the moment B)for the moment C)at the moment D)in a moment
答案是A,为什么不是C呢,请分析句子结构?

答案是C,为什么不是D,求分析?
答：It doesn't matter to me.对我来说,这无所谓（没关系）
It doesn't matter to me +主语从句.it为形式主语,真主是后面的这个主语从句:
which method you choose.你选择那一种方式.
翻译：对我来说,只要你准时完成任务,你选择何种方式去做都没关系.
再问： 前面几道题都回答的都很满意，解决了我的疑惑，只是，最后一道题。 no matter which 为什么不对呢？ 楼上说没no matter which ,我查了下，是有的。 请帮忙分析下。
再答： 答：no matter which ...是引导让步状语从句的，而此句中so long as引导的是条件状语从句，缺乏主句。
