Sentence Correction

Can I use certain word "can lead" with uncertain "would", or am I misunderstanding this sentence? Shouldn't this sentence have "possibly" to refer to the uncertainty of the event indicated by "would"?

Rising inventories, when unaccompanied correspondingly bv increases in sales, can lead to production cutbacks that would hamper economic growth.

(A) when unaccompanied correspondingly by increases in sales, can lead
(B) when not accompanied by corresponding increases in sales, possibly leads
(C) when they were unaccompanied by corresponding sales increases, can lead
(D) if not accompanied by correspondingly increased sales, possibly leads
(E) if not accompanied by corresponding increases in sales, can lead
=========================================================
The first thing we may notice is that the words possibly leads do not match with the subject Rising inventories. Answer choices (B) and (D) can be eliminated.

Does that answer your question?
