Task: Answer the MCQ question.
Query: Which drug exhibits a 1.216\% 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(COC(=O)CNC(=O)c1cccc([N+](=O)[O-])c1)Nc1nc2ccccc2s1
[b] O=[N+]([O-])c1ccc(C2CN=C(Nc3ccccc3)S2)cc1
Answer: a. O=C(COC(=O)CNC(=O)c1cccc([N+](=O)[O-])c1)Nc1nc2ccccc2s1
