B Correct answer
Explanation

In alternation of generations, haploid spores germinate to produce the gametophyte (haploid multicellular phase), which then produces gametes. The gametes fuse to form the zygote, which develops into the sporophyte (diploid multicellular phase). The sporophyte then produces haploid spores through meiosis, continuing the cycle. Haploid spores cannot directly produce a sporophyte - they must first produce the gametophyte.
