Task: Answer the multiple-choice question.
Question: Which drug exhibits a -8.723% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CN(C(=O)/C=C/c1ccccc1)C1CCS(=O)(=O)C1
b: CCCN(C(=O)c1ccc(OCC(C)C)cc1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c: O=C(C(=O)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1)c1cn(CC(=O)N2CCOCC2)c2ccccc12
d: COc1ccc(S(=O)(=O)CCc2nnc(NC(C)=O)s2)cc1
Answer: c. O=C(C(=O)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1)c1cn(CC(=O)N2CCOCC2)c2ccccc12
