Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.639\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CCOc1cc(CNCc2cccs2)ccc1OCC(=O)NC(C)(C)C.Cl
(b) Cc1ccc2c(Cl)c(C(=O)Nc3cccnc3)sc2c1
(c) O=C(Nc1ccc2ncccc2c1)c1cc(Cl)ccc1Cl
Answer: c. O=C(Nc1ccc2ncccc2c1)c1cc(Cl)ccc1Cl
