Task: Answer the multiple-choice question.
Question: Which compound has a 16.021\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(Cn1nc(C(=O)O)c2ccccc2c1=O)Nc1ccc(F)cc1F
b: COCCN(C(=O)c1ccccc1OC1CCN(S(C)(=O)=O)CC1)C(C)C
Answer: a. O=C(Cn1nc(C(=O)O)c2ccccc2c1=O)Nc1ccc(F)cc1F
