Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.238\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COc1ccc(-c2nn(-c3ccccc3C)cc2CNCc2cccnc2)cc1F
b COc1ccc(C2C(C(C)=O)=C(O)C(=O)N2CCc2ccccc2)c(OC)c1
Answer: b. COc1ccc(C2C(C(C)=O)=C(O)C(=O)N2CCc2ccccc2)c(OC)c1
