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 COCCNC(=O)C(=O)c1cc(C)n(-c2ccc([N+](=O)[O-])cc2)c1C?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
[a] 11.956
[b] 15.893
[c] -4.172
Answer: c. -4.172\%.
