Task: Answer the multiple choice question.
Question: Which compound exhibits a 16.431% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) C[C@@H](NC(=O)c1cc2c([nH]c3ccccc32)c(-c2ccccc2)n1)C(=O)O
(b) O=C(COC(=O)c1ccccn1)Nc1cccc2ccccc12
Answer: b. O=C(COC(=O)c1ccccn1)Nc1cccc2ccccc12
