Solution

The correct option is C Plerome
According to histogen theory by Hanstein, shoot apex has three zones, called as histogens.
Dermatogen (outermost layer) gives rise to epidermis.
Periblem (middle layer) gives rise to cortex and epidermis.
Plerome (innermost layer) gives rise to vascular tissue including pith.
Thus, the correct answer is option B.
