Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a compound with the SMILES Cn1cc([N+](=O)[O-])c(C(=O)Nc2cc(Oc3cccnc3)cc([N+](=O)[O-])c2)n1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a 18.599
b -68.298
Answer: a. 18.599\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
