 I  picked "D" on first shot. i insighted following reasons for elimination.

A. as much as that which is being emitted annually by all - Wrong due to great "Being"

B. as much annually as is emitted by the - HEre "The" is wrong as it talks about all Motors, not any particular.

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

D. that emitted annually by all - Correct.

E. that emitted annually compared to the - HEre "The" is wrong as it talks about all Motors, not any particular

此结构中A和B要是同类型的东西...所以我认为不能跟句子

A 中的不是句子吧，我把它想成 that指代里面的number，后面which从句是修饰that的。 像ls的ls说的，应该是错在being吧。

赞同cocodym.
那里提到numberl了？that 指代the total amount of pollutant，这个题中that 不能省略。
