Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -66.835% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) Nc1cc(=O)[nH]c(SCC(=O)Nc2ccc3c(c2)OCCO3)n1
b.) O=C1CC(=O)Nc2cc(S(=O)(=O)N3CCN(c4ccc([N+](=O)[O-])cc4)CC3)ccc2N1
c.) O=C(Nc1ccccc1Cl)Oc1ccc(-c2ccccc2)cc1
Answer: b. O=C1CC(=O)Nc2cc(S(=O)(=O)N3CCN(c4ccc([N+](=O)[O-])cc4)CC3)ccc2N1
