Step-by-Step Solution
The correct option is Cytokinin.
Explanation:\nCytokinins are plant hormones (phytohormones) that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also have effects on apical dominance, axillary bud growth, and leaf senescence.
- Auxin is mainly responsible for cell elongation and phototropism.
- Gibberellin promotes stem elongation, seed germination, and flowering.
- Abscisic acid is a growth inhibitor that promotes dormancy and wilting of leaves.
