Solution
The correct option is B Tapetum
The wall of the pollen sac is having four layers,
which are Epidermis, Endothecium, Middle layers, and Tapetum. Epidermis is
followed by Endothecium, 2-3 middle layers and the single layer of Tapetum.
Thus, Tapetum is the innermost layer of the anther wall. It surrounds the
sporogenous tissue. Tapetum nourishes the developing pollen grains.
So, the correct answer is B.
