Solution

The correct option is B Calyptrogen
In the root apex, the cells of promeristem differentiate into dermatogen, periblem and plerome. Dermatogen further produces new small celled tissue called as calyptrogen. Calyptrogen is the fourth histogen that produces root cap. Thus, the correct answer is option B.
