Solution

The correct option is A Endothecium
Anther is the male reproductive structure present in the plant, which contains the pollen grains. Inside the anther, there are a few layers of cells, which contain pollen grains. Endothecium is the fibrous tissue of the inner wall of an anther. It plays a predominant role in its dehiscence, which is the breaking down of the walls of anther so that the pollen are released to the outer environment. This will result in the pollination of the flower.
Thus, the correct answer is option B.
