Model Answer

(B) Prevent the chips from getting oxidised

Nitrogen is an inert gas. It prevents the chips from reacting with oxygen, which would cause oxidation (rancidity) of fats and spoil the chips.

Explanation

Nitrogen is used because it is chemically inert and does not react with the oils/fats in chips. Oxygen causes oxidation, making chips rancid and stale. This concept is linked to Chapter 1 (prevention of oxidation/rancidity). Option D is wrong — CO₂ is not the problem gas; Option C is the opposite of what nitrogen does; Option A is incorrect as nitrogen has no effect on crunchiness.
