Task: Answer the multiple-choice question.
Question: Which compound exhibits a 2.768\% 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) COc1cc(NC(=O)c2ccc3c(=O)n(Cc4ccco4)c(=S)[nH]c3c2)cc(OC)c1OC
(b) Cc1cc(C(=O)NNS(=O)(=O)c2cccc(Cl)c2)nn1C(C)(C)C
(c) CCOc1ccc(CN2CCN(C(=O)c3ccco3)CC2)cc1.O=C(O)C(=O)O
Answer: c. CCOc1ccc(CN2CCN(C(=O)c3ccco3)CC2)cc1.O=C(O)C(=O)O
