• A. bryophytes, pteridophytes and kelps
• B. bryophytes and pteridophytes only
• C. pteridophytes only
• D. bryophytes only

Answer 1

The correct option is A bryophytes, pteridophytes and kelps

Haplo-diplontic type of life cycle involves clear alternation of generations between a haploid gamete producing gametophyte and a diploid spore-producing sporophyte. The haplo-diplontic life cycle is seen in all bryophytes and pteridophytes, along with certain algae. It is also observed in certain algae like Ectocarpus, Polysiphonia and kelps.
