Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a drug with the SMILES CCCC1N2CC3([N+](=O)[O-])CN1CC([N+](=O)[O-])(C2)C3(C)C?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a 8.310
b 0.029
Answer: b. 0.029\%.
