Solution
The correct option is C Hard bast
Pericycle is the outermost layer of the stele. Stele is composed of all tissues inside the endodermis. Structure of pericycle differs in monocots and in dicots. In dicots, pericycle is in the form of isolated strips of sclerenchyma cells, which are lignified. Each patch is associated with phloem of vascular bundle. Such a pericycle is called as hard bast.
Epiblema are special epidermal cells present in rootlets. They are specially adapted for absorbing liquids. Phellem is outermost layer of cork cambium which is suberised.
Astrosclereid is a type of sclereid which is a large, radially branched structure.
Thus, the correct answer is option C.
