Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a compound with the SMILES COc1c(/C=C2\SC(=Nc3ccccc3Cl)NC2=O)cccc1[N+](=O)[O-]?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
(a) 13.823
(b) -7.562
Answer: a. 13.823\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
