Answer 1

(iii), (i), (ii), (iv)

Explanation:

The fossilized pterido-phyte Zosterophyllum is a genus of extinct early terrestrial plants that lacked leaves. The later-emerging seedless land plants with more intricate reproductive and leaf structures are called ferns. Ginkgo is a genus of gymnosperms that emerged after seed development. Despite being gymnosperms, the genus Gnetales is thought to be closely related to flowering plants.
