Task: Answer the multiple-choice question.
Question: Which compound has a -12.684% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccccc1N1CCN(C(=O)CN(C)S(=O)(=O)c2ccc3c(c2)c(=O)n(C)c(=O)n3C)CC1
b: CCC(CC)C1C(C#N)=C(N)Oc2cc(C)oc(=O)c21
c: Cc1ccnc(Cc2ccccc2)n1
Answer: b. CCC(CC)C1C(C#N)=C(N)Oc2cc(C)oc(=O)c21
