(B) typical angiosperm anther is bilobed,with each lobe having two theca (dithecous).In a transverse section,a typical microsporangium appears near-circular in outline.It is generally surrounded by four wall layers: epidermis,endothecium,middle layers,and tapetum.There are four microsporangia located at the corners,two in each lobe.Eventually,these microsporangia develop into pollen sacs and extend longitudinally all through the length of an anther and are packed with pollen grains.

How many microsporangia are located at the corners of a typical bilobed anther of angiosperm?
