该who还是whom？请高手详细指点下好吗？

35.Jimmy is always polite not only to his supervisors and colleagues but to anyone else___he thinks deserves of kindly consideration
A whose B whom C which D who

这种问题我一直不知道该who还是whom，为什么呢？这个句子中它做的什么语呢？可以给个详细的指点吗？还有这个话的意思，谢谢了，辛苦高手些了~！
我想也是whom，主要是为什么呢？？是个什么句子结构，可以麻烦分析下吗

who whom who/whom did you play tennis with ?用who还是whom啊！~ whom /who 什么情况下该怎么用？ Whom are you waiting for? 是对错？是WHO还是WHOM who and whom who,whom的用法 who与whom区别 who whom whose 什么时候用who whom who whom that的区别
