The number of people | flying first class on domestic flights | rose sharply in 1990, | twice as many as | the increase in the previous year.

The number of people...rose sharply in 1990, this completes the idea and intent of the sentence, now anything that we add will be a modifier. General idea of a modifier of this kind - it'll try and compare, give some exact count or something. Among B, C, D, and E; D and E sound better. next comes parallelism, "rose sharply in 1990", as compared to "the increase in the previous year". Using "in" is appropriate. So, in this context, D is right.

The OA is A, see file attached. We need more discussion here. I am still not convinced with the OA.

Not convinced either, it looks like the sharp raise in 1990 is doubling the increase of previous year. Like previous year if the raise is X, 1990's raise is making it 2x (previous year's)

In the origional sentence 'doubling' explains the effect of the 'rise' hence correct. No other option conveys this meaning of 'effect', hence option A is the correct one.
