Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.625\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CCOC(=O)c1ccc(Oc2nc(NC)nc(Nc3ccccc3)n2)cc1
[b] COC(=O)[C@H](C)NC(=O)Nc1ccc(OC)cc1OC
[c] Cc1ccc(-c2cc(C(F)(F)F)nc(SCC(=O)c3cccc([N+](=O)[O-])c3)n2)cc1
Answer: b. COC(=O)[C@H](C)NC(=O)Nc1ccc(OC)cc1OC
