Answer 1

Answer: (A)

A & B

Gibberellins are used to speed up the malting process in brewing industry. They increase the yield of malt from barley grains. Auxins promote flowering, i.e., in pineapples. They help to prevent fruit and leaf drop at early stages but promote the abscission of older mature leaves and fruits. Auxin also controls xylem differentiation and helps in cell division. Hence the correct answer is (B)
