The correct answer is

Vessels and Tracheids

The correct answer is option 3 i.e. Vessels and Tracheids.

The elements of xylem tissue that form interconnected water-conducting channels are Vessels and Tracheids. Both vessels and tracheids are elongated dead cells with thick lignified walls, which enable efficient water transport. Vessels are wider and arranged end-to-end, forming continuous tubes that allow rapid water flow. Tracheids are narrower and conduct water through pits in their cell walls, providing support along with conduction. Together, vessels and tracheids ensure effective water conduction from roots to other parts of the plant. The combination of these elements makes xylem tissue highly specialized for long-distance water transport.
