  3. CMiddle layers
  4. DTapetum

Correct answer

B. Endothecium

Step-by-step solution

The anther wall consists of four layers: epidermis, endothecium, middle layers, and tapetum. The endothecium is the sub-epidermal layer of the anther wall. The cells of this layer develop fibrous thickenings of -cellulose on their inner and radial walls. These fibrous thickenings are hygroscopic in nature and play a crucial role in the dehiscence of the anther to release pollen grains. Answer: Endothecium
