Answer

Correct option: A.
Epiblema, cortex, endodermis, pericycle
a
Anatomically, root is distinguishable into following layers or regions sequentially
Epiblema $\rightarrow$ Cortex $\rightarrow$ Endodermis $\rightarrow$ Pericycle $\rightarrow$ Vascular system $\rightarrow$ Pith
Epiblemais the outermost piliferous layer of root tissue.
