Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES CC1(C)C(=O)OC(/C=C/c2cccc([N+](=O)[O-])c2)C(C)(C)C1=O?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a: 20.790
b: 7.110
Answer: a. 20.790%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_10uM__names__noun} of a {#compound|drug!} with the {SMILES__description} {SMILES#}?
