Apples are generally wrapped in waxed paper to

1. prevent sunlight for changing its colour
2. prevent aerobic respiration by checking the entry of oxygen
3. prevent ethylene formation due to injury
4. makes the apples look attractive

Apples have lenticles on their skin so, they respire. They are wrapped in wax paper after harvesting so as to prevent the respiration and over ripening of the apples. Other options do not support the reason for wrapping apple into waxed paper.
