Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.462\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=C(Nn1c(SCc2ccc([N+](=O)[O-])cc2)nc2ccccc2c1=O)c1ccc(F)cc1
(b) CC1(C)CC(=O)C2=C(C1)N(Cc1ccccc1)C(=O)C2(NC(=O)C(C)(C)C)C(F)(F)F
(c) COCc1cc(C)nc(NCCc2ccccc2)c1C#N
(d) COc1ccc(OC)c(NC(=O)C(=O)N/N=C(\C)CC(=O)Nc2ccc(Cl)cn2)c1
(e) CC(=O)Oc1ccc2occ(-c3ccccc3)c2c1
Answer: c. COCc1cc(C)nc(NCCc2ccccc2)c1C#N
