Correct Answer:
Induction of cell division and delay in senescence
Explanation:
The cytokinin is a true cell division factor, promotes meristematic tissue regions. The cytokinin prevents distruction of chlorophyll in leaves.

So this effect of cytokinin is called as Richmond-Lang effect of senescence.
