Solution
The correct option is B Phellogen
Vascular cambium is a lateral cambium which is produced by intrafascicular (present between xylem and phloem) and interfascicular cambium. Vascular cambium adds phloem or xylem mother cell that differentiates into their respective cell types, thus, it causes secondary stellar growth. Hypodermis, the cortical cells present just beneath the epidermis, resume the meristematic activity and produce phellogen just beneath the epidermis. Phellogen is the extrastelar lateral meristem that produces extrasteler secondary tissue system. The cork cambium or phellogen produces phelloderm on inside and phellem or cork on outside thereby adding extrastelar secondary tissues.
Therefore, the correct answer is option B.
