Answer 1

Cytokinin is a plant hormone. It promotes cell division. It also delays the destruction of chlorophyll and protein. It shows delay of senescence in leaves and keeps leaves green for long time. So when cut or excised leaves are induced to root, it will remain green because root synthesizes cytokinin hormone.

Thus, the correct answer is option B.
