He called on another girl,_______was more suitable for the job.
A.he believed B.who he believed C.whom he believed ,可我觉得A,B,C都可以,为什么只选C呢?
上面写错了，是选B

He called on another girl,_______was more suitable for the job.A.he believed B.who he believed C.whom he believed ,可我觉得A,B,C都可以,为什么只选C呢?上面写错了，是选B
B
he believes 相当于插入语,因此前面的人称是主格的who
who (he believed) was more suitable for the job.

此为非限制性定语从句
所以排除A，至于B.只能用who的宾格形式引导为限制性定语从句

朋友，你的英文有待加强。如果选A，语法不通，根本没有这么说的，如果是A，应当改为He called on another girl,he believed she was more suitable for the job.
如果选B，在who前面不应该有逗号。所以只能选C，who和whom还是有一定差别的。

这句是主语从句，可以用that/whom he believe B中要用宾格 ，A不是一个完整的从句，
