Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES CN(c1ccccc1)c1nc(N)c([N+](=O)[O-])c(N2CCCC2)n1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a -11.907
b -6.138
Answer: a. -11.907%.
{#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#}?
