The correct option is B Lignin
- The hardness of a cell refers to the sturdiness of the cell wall because of the presence of lignin and cellulose present in them.

- They are mainly found regions of wood and bark as they provide rigidity and prevents deterioration.
- It also provides support to tissues of vascular plants and few algae.
- So, the correct answer is 'Lignin'.
