Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.633\% 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] CCOC(=O)C1=NN(C(C)=O)C2(CC(=O)N(c3cccc(C)c3)C2=O)C1
[b] O=C(Cc1cccs1)NCc1cccc(Cl)c1
[c] O=C(CN1CCN(S(=O)(=O)c2ccc3ccccc3c2)CC1)Nc1ccc(N2CCOCC2)cc1
Answer: a. CCOC(=O)C1=NN(C(C)=O)C2(CC(=O)N(c3cccc(C)c3)C2=O)C1
