Answer: The correct answer is-
A sporophyte can be described as the multicellular, diploid phase in the life cycle of plants and alga.
It is the dominant phase in higher plants ( such as angiosperms and gymnosperms) and undergoes alternation of generation with a haploid, gametophyte phase.
Sporophyte produces haploid spores ( having half the number of chromosome as their diploid parent cell) by a process of cell division called meiosis ( also termed as reductional cell division)
The spores fuse to form a dipolid zygote that undergoes mitotic division to produce the sporophyte again.
On the contrary, male and female gametophyte are already haploid.
Thus, second option is the right answer.
