Task: Answer the multiple choice question.
Query: Which compound exhibits a 10.503% 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: COC(=O)c1cccnc1-n1c(=O)c2cccnc2n(CC(=O)Nc2ccc(Br)cc2)c1=O
b: O=C(N[C@H](Cc1ccc(Cl)cc1)C(=O)O)OCC1c2ccccc2-c2ccccc21
Answer: b. O=C(N[C@H](Cc1ccc(Cl)cc1)C(=O)O)OCC1c2ccccc2-c2ccccc21
