Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 12.701\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CCOC(=O)c1nn(-c2ccccc2)c2nc(-c3ccc(OC)cc3)c(C#N)c(=O)n12
b.) CNC1=C([N+](=O)[O-])CC([N+](=O)[O-])=C(N2CCN(C(=O)Nc3cccc(C(F)(F)F)c3)CC2)N1C
Answer: b. CNC1=C([N+](=O)[O-])CC([N+](=O)[O-])=C(N2CCN(C(=O)Nc3cccc(C(F)(F)F)c3)CC2)N1C
