Question

Fruit wrapped in paper ripens faster than when kept in open air because (A) heat of respiration is retained better (B) a chemical in the paper helps fruit ripening (C) a volatile substance produced by the fruit is retained better and helps in ripening (D) the fruit is cut off from the ambient oxygen which is an inhibitor to fruit ripening

The paper serves to trap the ethylene (a volatile gas) given off by the fruit in a layer around it rather than let it dissipate. This gas causes the plant tissue to chemically relax and begins breaking down faster, hence the effect of ripening quicker.
