Solution

The correct option is C Suberin
Casparian strip is generally composed of lignin but sometimes it is composed of suberin. It is mainly formed by the deposition on the radial and transverse walls of the endodermis and is chemically different from the rest of the cell wall. It blocks the passive flow of materials, such as water and solutes into the stele of a plant. Thus, option C is correct.
