Task: Answer the multiple-choice question.
Question: Which compound exhibits a -4.304\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(CN1C(=O)c2cccnc2Oc2ccc(Cl)cc21)Nc1ccccc1F
[b] CCOC(=O)/C(C#N)=C\c1ccc(N2CCN(C)CC2)cc1
[c] CCOC(=O)C1CCN(C(=O)c2ccccc2NS(=O)(=O)c2ccc(F)cc2C)CC1
Answer: a. O=C(CN1C(=O)c2cccnc2Oc2ccc(Cl)cc21)Nc1ccccc1F
