Never before had taxpayers confronted so many changes at once as they had in the Tax Reform Act of 1986.

A)             so many changes at once as they had in.

B)             at once as many changes as

C)             at once as many changes that there were with

D)             as many changes at once as they confronted in

E)             so many changes at once that confronted them in

My question: The right answer is D but why B choice is wrong? Thanks a lot. 另外，OG里的这些解释我看的不是很明白，请大家帮忙解释一下，谢谢。如下：choice B and C awkwardly place at once between confronted and its direct object, changes.Furthermore, B illogically states that the Act itself was many changes, when the point is rather that it presented many changes, and as many.....that is an unidiomatic comparison.
