Answer 1

Answer: (B)

a - ii, b - v, c - iv, d - iii

Gibberellin is a plant hormone which is diterpene chemically. It is used to promote flowering and early seed production in conifers. Abscisic acid is a terpene chemically. It is a carotenoid derivative. It is involved in the seed development and maturation process. Adenine is a precursor of cytokinin plant hormone. Cytokinin is responsible for the growth of lateral shoot when apical dominance is inhibited due to decreased concentration of auxin hormone. Ethylene is a gaseous volatile plant hormone. Ethylene along with auxin induces root hair formation.

Thus, the correct answer is option B.
