Task: Answer the multiple choice question.
Query: Which compound has a 2.236\% 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) CCOc1ccc(N(CC(=O)NCc2ccco2)C(=O)CCC(=O)Nc2nccs2)cc1
(b) O=C(O)C1CCC(Cn2c(SCc3cc(=O)n4cc(Br)ccc4n3)nc3ccsc3c2=O)CC1
(c) CC(=O)Nc1ccc(/C(C)=N/NC(=O)CN(c2ccccc2Br)S(C)(=O)=O)cc1
Answer: a. CCOc1ccc(N(CC(=O)NCc2ccco2)C(=O)CCC(=O)Nc2nccs2)cc1
