选A removal是remove的名词形式，单从这一点上A就优于C了 但是manhattan上还讲到了另外一个方面 you can't use 'resulting from' as an adverbial modifier, as is done here. in general, 'resulting from' is only used as an adjective modifier, almost always without a comma, as in the pollution resulting from the chemical spill forced all the local residents to evacuate.
不过关于伴随状语我还有个疑问，我觉得这句话把result from后面去掉了的话还是一句话啊，只不过是意思不完整了而已：The cottontail rabbit population in Orange County , California, has increased uncheckedin recent years. 可是伴随状语不都是起一个补充作用的么，比方说：All night long he lay awake，thinking of the problem. 去掉后面的thinking of the problem，前面的一句话也成立啊，只不过是不知道这个人awake在做什么而已。
