Solution
The correct option is B Sclerenchyma
Cells of sclerenchyma are thick-walled and are usually lignified. These cells are generally long and pointed in shape. The thickness is due to the formation of secondary wall. At maturity, the cells are devoid of protoplast. The cell wall encloses a cavity lumen. On the cell wall, simple pits are present.
Thus, the correct answer is option B.
