Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.906\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) Cn1c(O)c(C=Nc2ccccc2)c(=O)n(C)c1=O
(b) Cn1cnc2ccc([N+](=O)[O-])cc2c1=O
(c) COc1cccc(-c2cccc(NC(=O)C3CCN(Cc4ccc(C)o4)CC3)c2)c1
Answer: b. Cn1cnc2ccc([N+](=O)[O-])cc2c1=O
