it is said that his lameness ————-an accident.

C resulted from 是对的.
A,led to=B resulted in =D brought about
原形分别是lead to ,result in和bring about“ 导致；产生”的意思,后面跟结果；而C,result from 后面跟原因,“因.产生；因.所致”的意思,符合题意.题目的意思是,“他的跛脚是因为一场事故所致.”
楼主请比较：His lameness resulted from an accident.=An accident resulted in / led to / brought about his lameness.
