Task: Answer the multiple choice question.
Query: Which compound has a 13.693\% 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: COc1cccc(NC(=O)COc2c(F)c(F)c(C(F)(F)F)c(F)c2F)c1
b: O=C(NNc1nc2c(F)cccc2s1)C1COc2ccccc2O1
c: COC(=O)c1ccc(CN2CCC(Oc3cccc(C(=O)N4CCOCC4)c3)CC2)cc1
d: CCOc1ccccc1C1C(C(=O)OC)=C(N)OC2=C1C(=O)CCC2
Answer: b. O=C(NNc1nc2c(F)cccc2s1)C1COc2ccccc2O1
