(B) Extrastelar secondary growth refers to the formation of tissues outside the vascular cylinder (stele). This process is primarily driven by the activity of the cork cambium,also known as the phellogen.

Together,these three layers (phellem,phellogen,and phelloderm) are collectively known as the periderm.
