Answer: (A)

Answer 2

Bryophytes are land inhabiting or terrestrial plants. They complete their vegetative phase on land but water is necessary for their reproductive phase i.e. for completion of life cycle. So bryophytes are known as amphibians of plant kingdom. Thallophytes have a plant body that is not clearly differentiated into root, stem and leaves. They do not have vascular tissues and so are always aquatic. Pteridophytes are most primitive vascular plants. They have developed vascular tissues and so they were the first vascular plants on land. Tracheophyte includes all vascular plants - pteridophytes, gymnosperms and angiosperms.
