128
(A) significantly compounding the effects of drug and alcohol abuse, which already are a cost to business
of
(B) significantly compounding the effects of drug and alcohol abuse, which already cost business
(C) significantly compounding the effects of drug and alcohol abuse, already with business costs of
(D) significant in compounding the effects of drug and alcohol abuse, and already costing business
(E) significant in compounding the effects of drug and alcohol abuse, and already costs business

[Reveal] Spoiler:
B

E. should be costs and not cost

I think that EFFECTS OF DRUGS AND ALCOHOL ABUSE are the subject of the which clause, therefore plural is needed.

Therefore B is the best answer
