Task: Answer the multiple-choice question.
Query: Which drug exhibits a -12.752% human ether-à-go-go related gene (hERG) inhibition at 10uM?
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)c1cc(S(=O)(=O)Nc2cc(OC)cc(OC)c2)c[nH]1
(b) O=C(CCc1nc2ccccc2c(=O)[nH]1)Nc1nnc(SCc2ccccc2)s1
(c) O=C(c1cc(Br)ccc1Cl)N1CCN(c2ncccn2)CC1
(d) CCc1ccc(CN2CCC(Oc3ccc(C(=O)NCc4ccccn4)cc3)CC2)o1
(e) Cc1ccc(NC(=O)C2CCN(C(=O)c3ccco3)CC2)cc1
Answer: c. O=C(c1cc(Br)ccc1Cl)N1CCN(c2ncccn2)CC1
