E. 20 percent of some thing is a number. Hence it should be twice the number reported.

In D, Assuming those refers to young adults, it changes the meaning of the sentence.

Just clarifying. The Survey was reporting the number i.e. the percentage not the adults. those is plural so it can not be a pronoun for number that is singular.

Hence E is the correct answer.

I would go with E too.

'Much' is used for things that can not be counted. e.g 'too much of exercise', 'much heavier', 'too much to talk' etc.
Since '20% of young adults' is a number, E would be the right choice.

I beg to differ here. Although the correct option is E its not for the reason quoted above.
20% is not a number since we dont know 20% of what. Hence much will be used along with any estimate stated in percentage. Had it been 20% of 1000 youth then many would have been appropriate.

as much as 10% of smokers die due to lung cancer..... (correct).
as many as 10% of smokers die due to lung cancer..... (Incorrect)
This is my own opinion. Let me know counterviews if any......
