Task: Answer the multiple choice question.
Query: Which compound has a 5.831% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(OCC(=O)N1CCCC1)c1cc(Cl)ccc1[N+](=O)[O-]
b: O=[N+]([O-])c1ccc(-c2ccc(C=Nc3cccc4ccccc34)o2)cc1
Answer: a. O=C(OCC(=O)N1CCCC1)c1cc(Cl)ccc1[N+](=O)[O-]
