The correct answer is B) Keeping in copper vessel.
Curd is acidic due to the presence of lactic acid produced during fermentation. Acidic substances can react with certain metals, such as copper, to form potentially harmful salts.
Keeping acidic food like curd in copper vessels is not recommended because the acid can react with the copper metal. This reaction can leach copper ions into the food, potentially leading to health issues if consumed regularly in significant amounts. Stainless steel, plastic, and glass are non-reactive materials commonly used for storing acidic food items safely.
