Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 9.609\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=[N+]([O-])c1cccc(S(=O)(=O)c2cccc([N+](=O)[O-])c2)c1
(b) Fc1ccc(C2CC(c3ccco3)=NN2c2ccccc2)cc1
Answer: a. O=[N+]([O-])c1cccc(S(=O)(=O)c2cccc([N+](=O)[O-])c2)c1
