Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.610% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCC(=O)c1ccc(N2CCN(C(=O)c3cc([N+](=O)[O-])ccc3N3CCN(C)CC3)CC2)c(F)c1
b: O=C(O)CC1Oc2ccc(Cl)cc2NC1=O
Answer: b. O=C(O)CC1Oc2ccc(Cl)cc2NC1=O
