Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.203% 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(CN1C(=O)c2ccccc2C1=O)Nc1cc([N+](=O)[O-])ccc1O
b: CC(C)c1ccc[n+](-c2nc([O-])sc2C=O)c1
Answer: a. O=C(CN1C(=O)c2ccccc2C1=O)Nc1cc([N+](=O)[O-])ccc1O
