Why is it unsafe to store curd in a copper vessel?

Answer and explanation

Correct answer: Acids in curd can react with copper

Curd contains lactic acid, so it is an acidic food. If it remains in a copper vessel, the acid may react with the metal and form copper salts. Depending on the amount and conditions, such contamination can make the food unsuitable or harmful to consume. Therefore option A is correct. Curd is not acid-free, and copper neither converts it into pure water nor invariably makes food sweet; these statements do not describe a chemical reaction.
