Question

During the Carboniferous period, the dominant plants, which formed the great coal beds, were mainly

• A. giant lycopods, horsetails and ferns
• B. gymnosperms
• C. tree lycopods and cycads
• D. tree like early vascular seed plants

Answer 1

The correct option is A giant lycopods, horsetails and ferns

During the Carboniferous period, the forests of seedless vascular plants that existed in the tropical swamp forests provided the organic material that became coal. During this period the terrestrial environments were dominated by vascular land plants such as the lycopods or club mosses, sphenopsids, Cordaites, giant horsetails, called calamites, seed ferns and true ferns.

So, the correct option is 'giant lycopods, horsetails and ferns'.
