Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES CCOc1ccccc1/C=C\c1nc(O)c([N+](=O)[O-])c(=O)[nH]1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a: 22.039
b: 5.907
Answer: b. 5.907%.
