Hint: For the transportation of water, these are very important, as it provides mechanical support also. It composed of many numbers of small, wide, and lignified dead cells and the absence of nucleus and cytoplasm.

Complete answer
Non-vascular plants are the most primitive forms of land vegetation. It doesn’t have the vascular tissue system which is important for transporting water and nutrients.
Example - bryophytes
-In the kingdom Plantae the characteristic that separates nonvascular plants from others is vascular tissue which consists of xylem and phloem is absent in them. Xylem vessels help in the transportation of water and minerals throughout the plant whereas phloem vessels help in the transportation of sugar and other nutrients throughout the plant.
-Multilayer epidermis or bark is absent in nonvascular plants which means that they don't grow very tall and remain low to the ground because they don't need a vascular system to transport water and nutrients.

Additional information
-Leaves, stems, and roots all are absent in non-vascular plants instead they have leaf-like, stem-like and root-like structures that function similarly to a leaf, stem, and roots.
Example - Bryophytes composed of hair-like filament cal rhizoids function like roots help to hold the plant in place. The plant also has a lobed leaf-like body called a thallus.
-Non-vascular plants have the alternation of generations in cycles between sexual and asexual reproductive phases and spend most of the time in the gametophyte phase and the sporophyte is completely dependent upon the gametophyte for nutrition because photosynthesis takes place in the plant gametophyte.
-The three main types of bryophytes are
Bryophyta (mosses),
Haptophyta (liverworts)
Anthocerotophyta (hornworts).

So, the correct answer is, "Xylem vessels".

Note:
-The vascular system that is xylem and phloem is absent in the non-vascular plant.
-They don't have a variety of specialized tissue. Phyllids like structures are present in the mosses and liverworts that look like leaves.
