Answer 1

The correct option is A Auxin

Auxins, help to initiate rooting in stem cuttings, an application widely used for plant propagation. Auxins promote flowering, e.g., in pineapples. Auxins also help to prevent fruit and leaf drop at early stages but promote the abscission of older mature leaves and fruits.

Thus, the correct answer is option A.
