Task: Answer the multiple choice question.
Query: Which compound has a -2.296\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) Nc1cc(-c2cccc([N+](=O)[O-])c2)[nH]n1
b.) CC(=O)c1ccc(OCC(O)CN2CCc3ccccc3C2)cc1.Cl
c.) Cc1cnc(C(=O)Oc2c(C)ccc(C)c2C)cn1
Answer: a. Nc1cc(-c2cccc([N+](=O)[O-])c2)[nH]n1
