Task: Answer the multiple choice question.
Question: Which compound has a 9.195\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. O=C1NC(=Nc2ccccc2)c2ccc([N+](=O)[O-])cc21
b. CC(C)CC(=O)NC1(C(F)(F)F)NC(=O)N(c2ccccc2)C1=O
Answer: a. O=C1NC(=Nc2ccccc2)c2ccc([N+](=O)[O-])cc21
