Task: Answer the multiple-choice question.
Query: Which compound exhibits a 2.298% 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(Nc1ccc2c(c1)OCCO2)c1ccc(Cl)c(Cl)c1
b: COCCn1c(=O)[nH]c2cc(C(=O)Nc3cccc(C(C)=O)c3)ccc2c1=O
Answer: a. O=C(Nc1ccc2c(c1)OCCO2)c1ccc(Cl)c(Cl)c1
