Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a compound with the SMILES CCNc1c([N+](=O)[O-])ncn1C?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
[a] -3.354
[b] 3.120
[c] 10.089
Answer: a. -3.354\%.
