Q. Why oil is not stored in galvanized iron pot?

Correct Answer: d) All of above

Explanation:
– Galvanized iron is coated with zinc. Oils (especially edible oils) contain free fatty acids and moisture.
– These acids react with zinc to form zinc soaps/compounds, which can be harmful (toxic) if ingested.
– The reaction also imparts off-flavors, discoloration, and accelerates rancidity, reducing oil quality.
– As zinc dissolves/reacts, the protective coating is damaged, leading to corrosion of the container.

Therefore, all listed reasons apply.
