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 CCOC(=O)N1CCN(c2cc(NCCO)c([N+](=O)[O-])c3nonc23)CC1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a. -0.372
b. 31.241
c. 13.413
Answer: b. 31.241%.
