Problem statement: Answer the multiple choice question.
Query: Which compound has a 3.997% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: N#CC1=C(N)OC2=C(C(=O)CCC2)C1c1cc2c(cc1Cl)OCO2
b: O=C(NNc1ncccc1Cl)c1c(Cl)cccc1Cl
Answer: b. O=C(NNc1ncccc1Cl)c1c(Cl)cccc1Cl
