Task: Answer the multiple-choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES Nc1ccc(-c2ccc(N)c([N+](=O)[O-])c2)cc1[N+](=O)[O-]?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
[a] 24.323
[b] 11.466
[c] -20.484
Answer: b. 11.466%.
