请问OG92题

92. 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

In my understanding, the chinese means is that "从1986年税制改革之后，纳税人还从来没有一下碰到过这么多的变化。" By this chinese explanation, we can see that the action, "Never before had taxpayers confronted " took place after Tax Reform Act of 1986, right?

My question is whether the past perfect tense, in "Never before had taxpayers confronted ", is acceptable?
