According to its proponents, a proposed new style of aircraft could, by skimming along the top of the atmosphere, fly between most points on Earth in under two hours.



A.According to its proponents, a proposed new style of aircraft could, by skimming along the top of the atmosphere, fly between most points on Earth in under two hours.

B.By skimming along the top of the atmosphere, proponents of a proposed new style of aircraft say it could fly between most points on Earth in under two hours.
C.A proposed new style of aircraft could fly between most points on Earth in under two hours, according to its proponents, with it skimming along the top of the atmosphere.
D.A proposed new style of aircraft, say its proponents, could fly between most points on Earth in under two hours because of its skimming along the top of the atmosphere.
E.According to its proponents, skimming along the top of the atmosphere makes it possible that a proposed new style of aircraft could fly between most points on Earth in under two hours.

我原来选的是E，但是答案是A.有没有谁能告诉我为什么？？是不是因为E里面的make it possible that 有错，只有make it possible to do 这种用法？
那么C又是为什么错喃？因为介词短语修饰的位置有误？？   D的错误是不是因为because of 后面只能加名词或者简单名词短语，而D中的后面的短语过于复杂？？

E的主语应该是“according to its proponents",  这个its所指代的东西

E is wrong.   Make it possible  , could, represent the same meaning.
no clear referent for " it"

answer should be A

A.According to its proponents, a proposed new style of aircraft could, by skimming along the top of the atmosphere, fly between most points on Earth in under two hours.

我不懂A里，既然是ACCORDING，主语却是 a proposed new style of aircraft

这怎么对的上呢？请教！
