Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 11.141\% 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 other words.
Options:
(a) COc1cccc(NC(=O)CCc2nnc3ccc(NCc4ccco4)nn23)c1
(b) CCCCOc1ccc(C(=O)NCC(=O)OCC(=O)N2CCN(S(=O)(=O)c3ccc(C)cc3C)CC2)cc1
(c) O=C(c1ccccc1Br)N1CCN(c2ccccn2)CC1
(d) S=C(Nc1ccccc1)N1CCn2c(nc3ccccc32)C1
(e) O=C(CSc1ccc(Cl)cc1)Nc1ccc(C2SCCS2)cc1
Answer: c. O=C(c1ccccc1Br)N1CCN(c2ccccn2)CC1
