Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.709\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) COc1ccc(S(=O)(=O)N2CCCC(C(=O)Nc3ccc(OC)c(OC)c3)C2)cc1
(b) O=C(c1[nH]ncc1-c1cccc(Br)c1)C1CO1
(c) CC(=O)Nc1ccc(-c2cc(C(=O)O)c3ccccc3n2)cc1
Answer: b. O=C(c1[nH]ncc1-c1cccc(Br)c1)C1CO1
