是reaction产生的硫酸和硝酸吧。


如果是D,那which指代的是前面的atmospheric water vapor,成了水蒸气produce硫酸和硝酸了。


对吗?我对语法从来没信心的说。

D is wordy and "which"creates confusions of the subject to lead the sentence-- "have produced ....,and "are highly corrosive".


E is the best by using "to " to lead the subject that it is the Acid rain and snow to "produce"sulfuric and acids.....


This is very symbolic grammer point you can may find in OG,so stick to OG...personally...
