Task: Answer the multiple choice question.
Query: Which compound exhibits a -5.089\% 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 O=S(=O)(Nc1ccc2c(c1)OCCO2)c1ccc(F)cc1
b Cc1ccc(NC(CC(=O)c2ccccc2)C(=O)O)cc1Cl
Answer: a. O=S(=O)(Nc1ccc2c(c1)OCCO2)c1ccc(F)cc1
