Which term refers to the diploid generation that produces spores by meiosis?

Explanation:
The diploid generation that produces spores by meiosis is the sporophyte generation. In organisms with alternation of generations, the sporophyte (2n) undergoes meiosis to form haploid spores, which grow into the haploid gametophyte. The gametophyte then produces gametes by mitosis, and fusion of gametes creates a new diploid zygote that develops into a sporophyte again. The gametophyte is the haploid generation, not the diploid spore-producing phase, and calling the diploid stage in general would not specify that meiosis occurs to make spores.
