Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COc1cc(/C=C(\C#N)c2nc3ccccc3[nH]2)c([N+](=O)[O-])cc1OCc1ccccc1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a 13.900
b 12.020
c 10.057
d 8.484
Answer: a. 13.900\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_1uM__names__noun} of a {#compound|drug!} with the {SMILES__description} {SMILES#}?
