Solution

The correct option is A Cytokinins
Cytokinins are a class of plant growth substances or phytohormones that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence.
