Show answer and explanation

Correct answer: (d) All of above

Explanation

Galvanized iron is coated with zinc, which reacts with acidic components in oil to form toxic zinc compounds.

The metal reaction also promotes rancidity, reducing the oil's quality, taste and safety.

Moisture and acidic impurities corrode the zinc layer, so all three reasons apply together.
