A. which B. that C. it D. what
我知道答案是C，但是不知道为什么，请详细解释，谢谢

Answer 1

这里it即指accident，(that/which) it resulted in是定语从句，修饰the damages。
本句意为：实话告诉你，这起事故及事故造成的损害使我感到如此害怕，以至于从那之后我几乎放弃开车了。
这里A和B两个选项是干扰项，若把that/which resulted in看成一个定语从句，that/which即指代the damages，此时定语从句中确实宾语，应该是result in sth, 所以这里the damages that/which resulted in并不完整，不是定语从句。
