Solution

The correct option is B a-e, b-d, c-f
Pollen grains are formed from microspores and this process is called microgametogenesis.
Anther has four lobes containing microsporangia in each lobe which develops further and become pollen sac.
Stamens are the male reproductive organs. In some plants, stamens aggregate together to form clusters which are called the cones or microsporophylls.
Hence, the correct match is:
a-e, b-d, c-f
So, the correct answer is B.
