A
theylack motile sperm
B
theylack seed
C
theylack vascular tissue
D
theylack true roots, stems and leaves
Explanation: 

Detailed explanation-1: -Bryophytes such as mosses and algae are non-vascular plants. They do not possess true roots, stems and leaves. Xylem and phloem are absent. Bryophytes include liverworts, hornworts and mosses.

Detailed explanation-2: -Mosses and liverworts (collectively known as bryophytes) are non-vascular plants, meaning that they lack the inner tubes that move water throughout them like other plants with roots, stems, and leaves.

Detailed explanation-3: -Like moss, liverworts grow in moist habitats. They also don’t have leaves, stems, or roots. Like moss, they use rhizoids to anchor themselves to the ground, rocks or trees.

Detailed explanation-4: -Bryophytes. Bryophytes have no roots, leaves or stems. Moss and liverworts belong to this group. They are flowerless plants that grow in clumps.

Detailed explanation-5: -No, mosses do not have true roots, stems, or leaves. Mosses attach themselves to the surfaces on which they grow using small, clinging structures called rhizoids. While they help attach the plant to surfaces, they do not draw in or transfer moisture and nutrients to the plant the way true roots do.
