A
Pine Tree
B
Horsetail
C
Rose
D
Fern
Explanation: 

Detailed explanation-1: -Ferns and moss are both examples of primitive plants. They are flowerless or seedless plants. Fern and Funaria both are flowerless and seedless.

Detailed explanation-2: -Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.

Detailed explanation-3: -Ferns are considered the most advanced seedless vascular plants and display characteristics commonly observed in seed plants. Ferns form large leaves and branching roots. In contrast, whisk ferns, the psilophytes, lack both roots and leaves, which were probably lost by evolutionary reduction.

Detailed explanation-4: -Ferns have spores instead of seeds. Ferns reproduce asexually, which means they don’t require fertilization.
