Match List I with List II : List I List II A Ethylene 1 Initiates rooting in stem cuttings B Auxin 2 Promotes rapid internode elongation in deep water rice plants C Cytokinin 3 Promotes bolting in rosette plants D Gibberellin 4 Helps overcome apical dominance Choose the correct answer from the options given below :

Step-by-step solution

Ethylene promotes rapid internode or petiole elongation in deep water rice plants, helping the leaves or upper parts of the shoot to remain above water. Thus, A matches with 2. Auxins are widely used in agriculture and horticulture to initiate rooting in stem cuttings, which is useful for plant propagation. Thus, B matches with 1. Cytokinins promote lateral shoot growth and help overcome apical dominance. Thus, C matches with 4. Gibberellins promote bolting, which is internode elongation just prior to flowering, in
