Solution

The correct option is D Ethylene
All of the given options are phytohormones (plant hormones).
Plant hormones control all the growth and development activities like cell division, enlargement, flowering, seed formation, dormancy and abscission. The major function of the given hormones are as follows:
A) Auxin- Cell elongation of stems and roots
B) Cytokinin- Promotes lateral and adventitious shoot growth by inducing cell division.
C) Ethylene- Hastens the ripening of fruits
D) Gibberellin- Breaks seed dormancy promotes flowering Hence, ethylene gas is used for the artificial ripening of fruits.
