Detailed explanation-1: -So, the correct answer is ‘Algae, moss, ferns, gymnosperm, angiosperms’

Detailed explanation-2: –Among those, primitive vascular plants come under the pteridophytes. They are commonly called ferns.-Ferns are usually well-differentiated which means they have well-developed roots, stems and all but when to come to life cycle it occurs by the spore dispersal, hence it is considered as the most primitive plant.

Detailed explanation-3: -Bryophytes are usually small plants that do not attain much height and remain close to the surface of the earth because they do not have efficient transport mechanism ie vascular system is missing. The primitive vascular system was first seen in Pteridophytes and which greatly evolved in Gymnosperms and Angiosperms .

Detailed explanation-4: -"Whisk Ferns” such as Psilotum. Lycopods such as Lycopodium, Selaginella, and Isoetes. Horsetails (Equisetum)

Detailed explanation-5: -Most primitive vascular plants are pteridophytes. Cycas belongs to gymnosperms. Gymnosperms have a well-differentiated plant body with vascular tissues. Moss belongs to bryophytes. Bryophytes have a well-differentiated plant body with stem and leaf-like structures. Brown algae belong to thallophytes.
