Gymnosperm

The correct answer is option B.

Explanation of correct option:

1. Gymnosperm is a seed-producing plant whose seeds are not enclosed in the ovary or fruit like in the angiosperms.
2. These plants develop on the surface of scales or leaves, or at the end of stalks forming a cone-like structure.
3. The seeds are open to the air and directly fertilized by pollination through the wind.
4. The seeds contain endosperm that stores food for the growth and development of the plant.
5. They are found in the colder regions and do not produce flowers.
6. Examples: conifers, cycads, gnetophytes, and the species of gynkgophyta.
7. The Giant Redwood Tree (Sequoia sempervirens) is also an example of a gymnosperm.

Option D

1. Pteridophytes is a vascular plant that reproduces using spores.
2. They do not produce flowers or seeds instead disperse spores.
3. They are well differentiated into roots, stems, and leaves.
4. Example includes whisk fern, Dicksonia, selaginella, etc.

Final answer:- The Giant Redwood Tree (Sequoia sempervirens) is a gymnosperm.
