Solution

The correct option is C Three
Cytokinins act along with other plant growth regulators. In association with auxins, cytokinins promote cell division and are considered as the true cell division factor. It plays a vital role in the morphogenesis of plants and is used in tissue culture experiments. In tissue culture, cytokinin in association with auxin promotes mitosis in the cells. Cytokinin helps in cell division, cell enlargement, and cell maturation.
