Answer:
In a transverse section, a typical microsporangium appears near circular in outline. It is generally surrounded by four wall layers - the epidermis, endothecium, middle layers, and the tapetum. The outer three wall layers perform the function of protection and help in dehiscence of anther release to release pollen. It nourishes the developing pollen grains. Cells of the tapetum possess dense cytoplasm and generally have more than one nucleus. The tapetum becomes multilayered during the microsporogenesis.
Hence, the correct answer is 'IV and II'
