In a nitrogen-filled packet, how are the oils in chips mainly prevented from becoming rancid?

Answer and explanation

Correct answer: Nitrogen displaces oxygen and slows the oxidation of oils

The oils present in chips can react with oxygen and become rancid through oxidation. Nitrogen is relatively inert and lowers the amount of oxygen in the packet, so oxidation of the oils slows down. The cushioning in option A may reduce chip breakage, but it does not prevent rancidity of the oils.
