Solution
The correct option is D Bryophytes
The plant body of bryophytes is not completely differentiated into roots, stems and leaves. They have small minute structures called rhizoids instead of roots. They are non-vascular plants. Water is necessary for reproduction in bryophytes. They have two stages in the life cycle. One is the gametophyte stage and second is the sporophyte phase. In their gametophyte phase, sperms and eggs are produced. The sperms can move through the water and reach the eggs to perform fertilization. So, option D "Bryophytes" is the correct answer.
