Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → B, A, D, C
Land plants evolved from simple spore-bearing forms to seed plants, and the flowering plants came last.
(B) Progymnosperms — come first. These were early woody plants that still reproduced by spores. They gave rise to the seed plants.
(A) Seed ferns — come second. They were the first plants to bear seeds, and they looked like ferns.
(D) Cycads — come third. They are gymnosperms. Their seeds are naked, and they were common in the age of the dinosaurs.
(C) Dicotyledons — come last. They are angiosperms, the flowering plants with seeds enclosed in fruits, and they appeared after the gymnosperms.
