Malcolm · Answer 1

Correct Sentence is (B) : significantly compounding the effects of drug and alcohol abuse, which already cost business

Explanation:

A is wrong as "which already are a cost to business of" is incorrect usage. the effects of drug and alcohol abuse [plural] - COST "is" required. So, C and E out. D is wrong because initial non-underlined part "the use ... is growing" which indicates it requires an adverb to indicate the emphasis and also u can see ", and already costing business" part in the end which add another clause rather than a modified form. So the correct one is B with correct grammar and word usage.
