Task: Answer the multiple-choice question.
Query: Which compound exhibits a -2.653\% 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(NCC(=O)NC(=O)NC1CCCC1)c1ccc(Cl)cc1Cl
b: O=S(=O)(NCc1ccccc1F)NCc1ccccc1F
Answer: b. O=S(=O)(NCc1ccccc1F)NCc1ccccc1F
