(c) Refers to cell movements

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. In presence of kinin the rate of mitotic cell division gets increased. Under this effect when green leaves are kept in cytokinin solution then they become green for long time. So this effect of cytokinin is called as Richmond-Lang effect of senescence.
