(C) According to the Histogen theory proposed by Hanstein,the root apex of dicotyledonous plants consists of three distinct layers of meristematic cells,known as histogens:$1$. Dermatogen: The outermost layer that gives rise to the epidermis (epiblema).$2$. Periblem: The middle layer that develops into the cortex.$3$. Plerome: The innermost core that forms the stele (vascular cylinder).Therefore,there are $3$ histogens present in the root apex of dicots.

How many histogens are present in the root apex of dicots?
