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 Nc1c(-c2cccc([N+](=O)[O-])c2)nc2ccccn12?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a: 14.603
b: -18.502
c: 2.084
Answer: b. -18.502%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
