Answer:
The correct match would be:
1. gametophytes
2. gametes
3. zygote
4. sporophyte
It represents the alternation of generation in which a diploid sporophyte with the help of meiosis produces haploid spores.
The spores develop into haploid gametophytes which produce gametes (egg and sperm) with the help of mitotic division.
The male and female gametes fertilize to produce a diploid zygote which matures into the diploid sporophytes.
