My answer is (C). It took me 34 seconds.

"Last year" is a strong signal that simple past tense should be used in the main clause. Eliminate (ABD).

The difference between "having wiped out" in (E) and "wiping out" in (C) is that
"having wiped out" indicates that "wiping out" occurred before "output fell"
while
"wiping out" points out the consequence of "falling output".

Without additional context, the interpretation of "wiping out" is more reasonable. That is not to say that "having wiped out" is always wrong.

I think it should be (E), if we are to continue to with correct tense throughout the sentence, then 'having wiped out' would be correct.
