Correct answer
D. A -1 , B -4 , C - 3, D - 2
Step-by-step solution
A typical angiosperm anther is bilobed with each lobe having two theca, i.e., they are dithecous Two parts of a typical stamen – the long and slender stalk called the filament The process of formation of microspores from a pollen mother cell (PMC) through meiosis is called microsporogenesis. Pollen grains are generally spherical measuring about 25-50 micrometers in diameter
