Which metal is generally used for coating of brass utensils to prevent copper contamination ?

Correct Answer: A. Tin

Explanation: Tin is the metal generally used for coating brass utensils to prevent copper contamination and corrosion, creating a non-toxic barrier between the metal and food. This process, known as tinning or kalai in India, is essential because brass contains copper, which can react with food acids and form harmful compounds or a greenish, corrosive coating of copper carbonate.
