The correct option is D Brachysclereids
The common guava or the Psidum gujava is a small tree from the Myrtaceae family. The firmness of guavas and Pyrus is due to the presence of compact parenchyma cells, which may be round, polygonal, polyhedral, and of different sizes but streaked with grouped sclereids (stone cells) giving the pulp a granular texture.
Thus, the correct answer is option D.
