Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Application of cytokinins to marketed vegetables can keep them fresh for several days. Shelf life of cut shoots and flowers is prolonged by employing the hormone cytokinin. The reason is that the cytokinin increases retention of chlorophyll and delayed senescence in leaves. Cytokinin as the name suggests, is essential for cell division or cytokinesis. It promotes cell division along with auxin by controlling the activity of cyclin dependent kinases.
