Task: Answer the multiple-choice question.
Question: Which drug has a -4.726% 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: O=C(CN1CCN(c2ccccn2)CC1)Nc1ccc(Oc2ccccc2)cc1
b: C/C(N)=C(/C#N)C(=O)COC(=O)CCC1CCCC1
c: CN(C)S(=O)(=O)c1ccc(S(=O)(=O)N(Cc2ccco2)Cc2ccccc2Cl)cc1
Answer: b. C/C(N)=C(/C#N)C(=O)COC(=O)CCC1CCCC1
