Solution

The correct option is B Gibberellin – stem elongation
Auxin, gibberellin, cytokinin and ethylene are hormones that are present in plants. Gibberellins help in stem elongation, seed germination, breaking dormancy, etc. Auxin, produced in the apical part of the plant, helps in enlargement of cells. Cytokinin brings about cell division. Abscisic acid inhibits growth of the plant.
