The concept of 'Dedifferentiation' in relation to meristem formation is best exemplified by:
Activity of the root apical meristem
Formation of interfascicular cambium from parenchyma cells
Development of phellogen from the epidermis
Differentiation of xylem vessels from procambium

Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R :
Assertion A : The shoot apical meristem transforms into the floral meristem, giving rise to a flower, a modified shoot.
