Correct answer: D
Based on their mode of reproduction, plants are classified into two broad groups: Cryptogams, which are flowerless plants that reproduce through spores (algae, fungi, bryophytes, and pteridophytes such as ferns), and Phanerogams, which are seed-bearing plants with true flowers. Phanerogams are further divided into Gymnosperms, whose seeds are 'naked' and not enclosed within a fruit, and Angiosperms, whose flowers develop into a fruit that encloses the seed.
The question asks for the group of plants that bear flowers, fruits, and seeds together — all three features in one plant.
Cryptogams reproduce by spores, not seeds, and never produce flowers or fruits, so this group does not fit.
Ferns are a type of cryptogam (a pteridophyte); like other cryptogams, they reproduce by spores and never bear flowers, fruits, or seeds.
Gymnosperms do produce seeds, but the seeds sit exposed on the surface of cone-like structures rather than being enclosed in a fruit, and gymnosperms lack true flowers.
Angiosperms produce true flowers, and after fertilisation the ovary of the flower develops into a fruit that encloses the seed(s) — matching all three features in the question.
A mango tree is a familiar example: its flower develops into a mango fruit with the seed inside — a hallmark of Angiosperms. A pine tree, by contrast, is a Gymnosperm: its seeds are exposed on the scales of a cone, with no flower or fruit involved. This confirms that flowering plants bearing flowers, fruits, and seeds together are called Angiosperms.
