Task: Answer the multiple-choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES CCCCn1c(=O)c(F)cn(Cc2ccc(OC)c([N+](=O)[O-])c2)c1=O?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a -25.154
b -22.593
Answer: a. -25.154%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
