Solution

The correct option is B Ethylene
Ehtylene is a simple gaseous plant growth regulator. It is synthesized in large amounts by tissues undergoing senescence and ripening of fruits. It enhances the respiration rate during ripening of fruit. This rise in rate of respiration is called as respiratory climacteric.
Exposure of plants to ethylene causes drooping of leaves and flowers, a phenomenon known as epinasty.
Thus, the correct answer is option B.
