Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES CCNCCNc1ccc([N+](=O)[O-])c2cccnc12?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any additional words.
Options:
