What type of change occurs when milk is converted into curd?
Answer and explanation
Correct answer: Chemical change
Milk changes into curd through bacterial fermentation, mainly involving the conversion of lactose into lactic acid. New substances form, the composition changes, and the properties of curd differ from those of milk; therefore, it is a chemical change and option B is correct. It is not merely a change of state, shape, or physical appearance, and the process is not readily reversible.
