Providing initial evidence that airports are a larger source of pollution than they were once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O’Hare International Airport is twice as much as that which is being emitted annually by all motor vehicles in the Chicago metropolitan area.

A.as much as that which is being emitted annually by all

B.as much annually as is emitted by the

C.as much compared to what is annually emitted by all

D.that emitted annually by all(D)

E. that emitted annually compared to the

这个题就是对比较部分我有点疑问，我觉得twice前面是指the total amount，D的比较的后半部分是that emitted annually by all motor...，应该这里that指代的是pollutant吧，是total amount of pollutant吗？不是太确定，请斧正啊。
