C.      all the other planets, each of which contributing according to its

D.      all the other planets, each contributing according to its

E.       all the other planets, each of which contribute according to their

我像说的是D选项中，“that emitted annually by all  ”  that 应该指代pollutant 才对            ，因为原文中这样写道 total amount of pollutant emitted annually by vehicles ，明显emitted 实在修饰pollutant  ,而作者又在比较amount,若that 指代amount，则the amount emitted annually by all 有明显的逻辑错误，偶个人认为此题无正确答案
