Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -9.789\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a COC(=O)c1sccc1N/N=C(\C)c1ccc(F)c(Cl)c1
b CC(C)c1nnc(NC(=O)CCC(=O)N2CCN(c3cccc(Cl)c3)CC2)s1
c COC(=O)CSc1nnc(COc2ccc([N+](=O)[O-])cc2)n1C
d O=C(COc1cccc2ccccc12)Nc1cc(S(=O)(=O)N2CCOCC2)ccc1N1CCOCC1
e OC(CNCc1ccccc1)(c1ccc(F)cc1)c1ccc(F)cc1
Answer: c. COC(=O)CSc1nnc(COc2ccc([N+](=O)[O-])cc2)n1C
