Task: Answer the multiple choice question.
Question: Which compound has a 14.631\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=c1c2ccccc2cnn1Cc1ccc(Cl)c(Cl)c1
[b] CCC(Oc1ccccc1)C(=O)Nc1ccccc1N1CCCC1
[c] CCOC(=O)C1CCN(C2=NC(=O)/C(=C/c3ccc(Cl)cc3)S2)CC1
[d] COc1ccc(CNC(=O)CN2C(=O)CC(c3ccccc3)=Nc3ccccc32)cc1
Answer: a. O=c1c2ccccc2cnn1Cc1ccc(Cl)c(Cl)c1
