Apples are generally wrapped in waxed paper to
(a) Prevent sunlight from changing its colour
(b) Prevent aerobic respiration by checking the entry of O2
(c) Prevent ethylene formation due to injury
(d) Make the apples look attractive

The answer is the option (b) Prevent aerobic respiration by checking the entry of O2 .
To avoid the ripening of the apple, in order for it to stay fresh for a much longer time, aerobic respiration is prevented because it makes the apple rot much faster.
