我不知道是因为甚麽语法的原因， 这里要这样用
但我可以肯定的告诉你， 以下的两个说法， 都是对的

I could not see clearly who it was they were talking to
I could not see clearly whom they were talking to

没有 ..... whom it was they were talking to 的说法

就是B

这里最主要是说明it was who ，who 在句子里就是主语了。你说的没错，talk to sb 应该用宾格whom,这里就是省略了这个whom。把后面这句用陈述来表述应该是这样 it was who (whom) they were talking to.其实括号里的whom可以省略

who lt was后断句，后面是定语从句修饰前面，who作宾语。相当they were talking to 前省略了that.

talk to sb.其中的sb就是宾语啊，如talk to her,talk to me

这是一个强调句型，基本句型是It +be动词+强调部分（可以是主语、宾语、状语）＋that剩余部分。当强调人时，可用who，其余都为that。这是是把talk to的宾语whom省略，而强调句型的who提前了。
