Answer:
Correct Answer: B
Solution:
Abscission involves formation of a special parenchymatous layer called abscission or separation layer at the base of organ and a layer of suberised thick-walled ‘cork’ cells called protective layer over the mother axis.
Degeneration of cells of abscission or separation layer causes abscission.
