Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.168\% 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 or b without using any other words.
Options:
a. O=C(Nc1ccc(Cn2cccn2)cc1)c1ccc(COc2cccc(Br)c2)cc1
b. O=[N+]([O-])c1ccc(Nc2ccc(Oc3ccc([N+](=O)[O-])cc3[N+](=O)[O-])cc2)c([N+](=O)[O-])c1
Answer: b. O=[N+]([O-])c1ccc(Nc2ccc(Oc3ccc([N+](=O)[O-])cc3[N+](=O)[O-])cc2)c([N+](=O)[O-])c1
