Can you please mention where do you get this problem from ?

Anyway, this is what I think -

D - 'twice' is more appropriate when you have mentioned a specific number. Here the sentence compares the 'increment' of two years, hence 'doubling' is the right word.

Also, 'increase of' is preferred rather than 'increased in'.

"twice as many as" refers to people, so people can't be compare with "increase". people can only be compared with people, increase in one year can be compared with increase in another!!

I understand the sentence in the following way: the number of people risen sharply in 1990 doubled the increase of the previous year. we are comparing "increase", so 'doubling' seems more appropriate

I FOUND THIS EXPLANATION ON MANHATTAN FORUMS POSTED BY ONE OF THE TUTORS-RON

HTH

in this case, you can't use "..., twice as many as...", because that's an appositive modifier. appositives must modify some noun that comes IMMEDIATELY before the comma, which in this case would have to be whatever figure is twice whatever other figure. since no such figure is given, you can't use this construction.

so, A, B or C

by contrast, the -ING FOLLOWED BY A COMMA modifies the entire action of the preceding clause. this is exactly what you want to happen, because the actual rising of the # of people flying first class is what "doubled the increase of...". there's no noun in there that pinpoints this concept, so you have to use a modifier that modifies the entire clause.
