Detailed explanation-1: -Enzymic browning is a reaction which requires the action of enzymes and oxidation in order to occur. What happens during enzymic browning? Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction).

Detailed explanation-2: -Its basically an oxidation reaction which involves chemical reactions so the phenomena is a chemical change. Q.

Detailed explanation-3: -When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.
