Solution

The correct option is A Promotes bolting
Auxin is a plant hormone. It is involved in various physiological processes of the plant. It promotes apical dominance by inhibiting the growth of lateral buds. It promotes flowering in certain plants like pineapple by increasing production of ethylene. It prevents early fruit and leaf drop. However, it causes abscission of older leaves. After stem cutting, it initiates rooting.
Thus, the correct answer is option A.
