Archegonia
B
Lack of vascular tissue
C
Swimming antherozoids
D
Independent gametophyte
Explanation: 

Detailed explanation-1: -Plants belonging to division bryophyta do not have any specialised tissue for conduction of water and other substances. They are non-vascular plants. On the other hand, in pteridophytes, the plant body is differentiated into roots, stems and leaves.

Detailed explanation-2: -Bryophytes (phylum Bryophyta) are plants that lack true vascular tissues and organs.

Detailed explanation-3: -The main distinguishing feature of pteridophyta is the presence of vascular tissue for conduction. Indeed, pteridophytes are thought to be the first vascular plants to have evolved on Earth. Xylem and phloem are types of vascular tissue. However, these plants have only primitive xylem and phloem.

Detailed explanation-4: -They do not have conducting or vascular tissues, i.e, xylem, and phloem.

Detailed explanation-5: -bryophyte sporophytes are very small structures and are connected to their gametophytes for its nutrition and health. It comprises a single unbranched tail, or seta, and a stalk called the terminal sporangium. Hence the bryophytes lack the true roots and the vascular tissue.
