Correct answer: (b) microspore
Explanation:
In seed plants the microspores develop into pollen grains each containing a reduced, multicellular male gametophyte whereas megaspores develop into female gametophyte. The male gametophyte gives rise to sperm cells, which are used for fertilization of an egg cell to form a zygote.
