Task: Answer the multiple choice question.
Question: Which compound has a 13.123\% 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] CN(O)/C=C/C(=O)c1ccc(Br)cc1
[b] O=C(O)C1CN(c2nc(Cl)ccc2[N+](=O)[O-])C1
[c] O=C(Nc1ccncc1)C1c2ccccc2Oc2ccccc21
Answer: b. O=C(O)C1CN(c2nc(Cl)ccc2[N+](=O)[O-])C1
