Solution

The correct option is B Cork
Suberin is a waxy substance present in the thickened cell walls of many trees and shrubs, particularly in cork tissues. The cork cells gradually lose their protoplast and become dead and their cell walls become suberized. The deposition of suberin (suberization) provides a water protective layer.
Thus, the correct answer is option B.
