Task: Answer the multiple choice question.
Query: Which compound exhibits a 4.909\% 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 other words.
Options:
a: COC1=CCC2([N+](=O)[O-])CN(CC(=O)O)CC1([N+](=O)[O-])C2
b: Cl.Nn1cnnc1N/N=C/c1ccc(Cl)c([N+](=O)[O-])c1
c: O=C(Cn1nc(C(F)(F)F)cc1C1CC1)Nc1ccccc1F
Answer: b. Cl.Nn1cnnc1N/N=C/c1ccc(Cl)c([N+](=O)[O-])c1
