Problem statement: Answer the multiple choice question.
Query: Which compound has a 9.766\% 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: O=C(CN(Cc1ccc(Cl)cc1)C(=O)CN1C(=O)COc2ccccc21)NC1CCCC1
b: O=C(CNC(=O)C(c1ccccc1)c1ccccc1)N/N=C/c1ccc(O)c([N+](=O)[O-])c1
c: O=C(NCCc1ccccn1)c1cc(-c2ccccc2Cl)nc2ccccc12
Answer: b. O=C(CNC(=O)C(c1ccccc1)c1ccccc1)N/N=C/c1ccc(O)c([N+](=O)[O-])c1
