The correct answer is: Gibberellic acid - Leaf fall
Gibberellic acid is a growth promoter thus it inhibits leaf fall. Abscisic acid is commonly called stress hormone and it promotes closure of stomata. Cytokinin promotes cell division. IAA is an auxin that induces cell elongation and cell division resulting in plant growth and development.
