Task: Answer the multiple choice question.
Question: Which compound has a 8.937\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(O)CC(NC(=O)C(c1ccccc1)c1ccccc1)c1ccco1
b: O=[N+]([O-])c1ccccc1Oc1ccc(Cl)c2cccnc12
c: O=C(N/N=C/c1ccccn1)c1ccc(NC(=O)c2cccc([N+](=O)[O-])c2)cc1
d: O=C(Nc1ccc(Cl)cn1)c1cc2ccccc2o1
e: COc1ccc(-c2nc(-c3cccc(C(F)(F)F)c3)no2)cc1OC
Answer: b. O=[N+]([O-])c1ccccc1Oc1ccc(Cl)c2cccnc12
