Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (C), (D), (B), (A)
(C) Rhynia type plants — first. In the book’s chart of plant evolution, Rhynia-type plants sit at the base, in the Silurian, just above the tracheophyte ancestors. They were among the earliest land plants with vascular tissue.
(D) Psilophyton — second. Psilophyton comes next, at the Silurian–Devonian boundary. From it the lines leading to ferns, horsetails, lycopods and seed plants branch off.
(B) Seed ferns — third. Seed ferns arise from the progymnosperms in the Devonian–Carboniferous.
(A) Angiosperms — fourth. Flowering plants branch off from the seed-fern line and spread widely in the Cretaceous and Tertiary.
