Suberin is a waxy substance, similar to cutin, present in the thickened cell walls of many trees and shrubs, particularly in cork tissues. The outer cork cambium gradually loses 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 C.
