The correct option is B
Chemical change

Here after the cutting the apples into slices and leaving it for sometime will result into brown coating because apples are exposed to oxygen present in air, the action damage the cells of the fruit, allowing oxygen in the air to react with the enzymes and other chemicals present in the apple. Hence it is a chemical change.
