Task: Answer the multiple-choice question.
Question: Which drug has a -12.307\% 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: CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](c2ccc(C(F)(F)F)cc2)[C@@H]1CCCO
b: Cc1csc(=O)n1CC(=O)OCC(=O)Nc1ccc(F)c(F)c1
c: O=C(CN1CCN(Cc2ccccc2Cl)CC1)N/N=C/C=C\c1ccccc1[N+](=O)[O-]
d: COCCn1c(SCC(=O)Nc2ccc3c(c2)OCCO3)nnc1-c1c[nH]c2ccccc12
e: Cc1ccc(Cl)c(OCC(=O)N2CCc3ccccc3C2)c1
Answer: c. O=C(CN1CCN(Cc2ccccc2Cl)CC1)N/N=C/C=C\c1ccccc1[N+](=O)[O-]
