Task: Answer the multiple choice question.
Query: Which compound exhibits a -15.231% human ether-à-go-go related gene (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. COc1ccc(CCNC(=O)CSc2nn3c(=O)c(C)nnc3s2)cc1OC
b. CC(C)(C)Nc1nc(Cl)nc(NC(C)(C)C)n1
c. O=C(Nc1cccc(S(=O)(=O)N2CCOCC2)c1)c1cc([N+](=O)[O-])ccc1N1CCOCC1
d. CC(=O)c1ccc(N2CCN(S(=O)(=O)c3cccc4nonc34)CC2)cc1
Answer: c. O=C(Nc1cccc(S(=O)(=O)N2CCOCC2)c1)c1cc([N+](=O)[O-])ccc1N1CCOCC1
