Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.136% human ether-à-go-go related gene (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: Cc1cc(OCC(=O)Nc2ccc(CN3CCOCC3)cc2)ccc1Cl
b: O=C(Nc1cccc([N+](=O)[O-])c1)Nc1cccc([N+](=O)[O-])c1
Answer: b. O=C(Nc1cccc([N+](=O)[O-])c1)Nc1cccc([N+](=O)[O-])c1
