Task: Answer the multiple-choice question.
Query: Which compound exhibits a 10.913\% 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 other words.
Options:
a. CC(NS(=O)(=O)c1ccc2c(c1)OCCO2)c1ccccc1
b. O=C(CNC(=O)c1ccccc1F)OCc1nc2ccccc2s1
Answer: b. O=C(CNC(=O)c1ccccc1F)OCc1nc2ccccc2s1
