Task: Answer the multiple-choice question.
Question: Which drug has a 7.856% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(NCc1ccco1)C12CN(Cc3ccccc3)CC1C(c1ccc([N+](=O)[O-])cc1)=NO2
[b] O=C(Cn1cnc([N+](=O)[O-])c1)NCc1ccc(F)cc1
Answer: b. O=C(Cn1cnc([N+](=O)[O-])c1)NCc1ccc(F)cc1
