A
tall with xylem tubes
B
many leaves
C
no roots, stems, or leaves
D
conifers
Explanation: 

Detailed explanation-1: -They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).

Detailed explanation-2: -Nonvascular plants do not have roots, stems, and leaves, and they do not have vascular tissues within them, and they grow only in moist environments. 9. What are the 3 types of nonvascular plants? Mosses, liverworts, and hornworts are the three types of nonvascular plants.

Detailed explanation-3: -Bryophytes such as mosses and algae are non-vascular plants. They do not possess true roots, stems and leaves. Xylem and phloem are absent.

Detailed explanation-4: -These are the nonvascular plants or bryophytes (mosses, liverworts, and hornworts), the seedless vascular plants (clubmosses and ferns including, horsetails, club mosses, and whisk ferns), gymnosperms (conifers, cycads, Ginkgo, and gnetophytes), and angiosperms, or flowering plants.

Detailed explanation-5: -Vascular plants have roots not only for support but also to soak up water that is farther away from the plant. Nonvascular plants are commonly found in moist environments so that they are always close to a water source and can absorb the water right into the main part of the plant without relying on roots.
