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 CCOC(=O)c1sc2cc([N+](=O)[O-])cc(SCC(C)C)c2c1N?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a: 12.963
b: 3.763
c: 8.848
Answer: a. 12.963\%.
