Task: Answer the multiple choice question.
Query: Which compound exhibits a 0.725% 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: COc1ccc(S(=O)(=O)N(CC(=O)Nc2cc(C)on2)Cc2ccccc2)cc1
b: O=C1CCC(C(=O)OCc2cc(Cl)ccc2OC(F)F)N1
Answer: b. O=C1CCC(C(=O)OCc2cc(Cl)ccc2OC(F)F)N1
