Task: Answer the multiple choice question.
Question: Which drug exhibits a 27.570\% 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 other words.
Options:
(a) O=C(c1ccc(Cn2cc(Br)cn2)cc1)N1N=C(C(F)F)CC1(O)C(F)F
(b) CCOc1cccc(C2/C(=C(/O)c3ccc4c(c3)CC(C)O4)C(=O)C(=O)N2Cc2ccncc2)c1
(c) O=C(COC(=O)c1ccncc1)Nc1cc(Cl)c(Cl)cc1Cl
Answer: b. CCOc1cccc(C2/C(=C(/O)c3ccc4c(c3)CC(C)O4)C(=O)C(=O)N2Cc2ccncc2)c1
