Solution

The correct option is D Middle layers lie between endothecium and tapetum
Each anther lobe develops two pollen sacs. Thus, a two lobed anther develops four pollen sacs situated at four corners of the anther. The wall layers from periphery to centre consist of:
A single layer of epidermis
A single layer of endothecium
One to three middle layers
A single layer of tapetum
