Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES CCN1CCN(Cc2nc3ccc([N+](=O)[O-])cc3c(=O)n2-c2ccc(OC)cc2OC)CC1?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a -19.298
b 10.678
Answer: a. -19.298\%.
