Solution

The correct option is B senescence
Senescence is defined as the deterioration of the whole plant or plant organs due to loss of functional activity that ultimately leads to death. It is the last stage of development in plants.


Abscission is the process by which the senesced part of the plant is separated from the plant.

Dormancy is the state of inactivity when normal physiological functions are suspended or slowed down for a time period.

Juvenescence is the state in an organism’s developmental cycle when it is young.
