Task: Answer the multiple-choice question.
Query: Which compound exhibits a 13.243% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(COC(=O)C1=COCCO1)Nc1ccc2c(c1)OCO2
b: O=S(=O)(NCCCCCNS(=O)(=O)c1c(F)cccc1F)c1ccc2c(c1)OCCO2
Answer: a. O=C(COC(=O)C1=COCCO1)Nc1ccc2c(c1)OCO2
