Task: Answer the multiple choice question.
Query: Which compound has a 15.977\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1cc(C2C3CN(C)CC=C3C(C#N)=C(N)C2(C#N)C#N)ccc1OC(C)C
[b] O=C(CCc1nnc2ccc(NCc3ccco3)nn12)Nc1cc(F)ccc1F
[c] Cl.O=C(N1CCN(Cc2ccccc2)CC1)C12CC3CC(CC(C3)C1)C2
[d] O=C(Cn1c(C(=O)O)cc2ccccc21)c1ccccc1
Answer: d. O=C(Cn1c(C(=O)O)cc2ccccc21)c1ccccc1
