Correct answer: C

Senescence is an active developmental cellular process in the growth and functioning of a flowering plant, indicated in lead abscission. Senescence is the changes that occur in an organism between maturity and death, i.e., ageing.

Characteristically there is a deterioration in functioning as the cells become less efficient in maintaining and replacing vital cells components.
