Solution
The correct option is B Xylem
Xylem is a water conducting tissue, made up of tracheids, trachea, xylem fibers and xylem parenchyma of which the first three are dead cells and the last one is living. Tracheids have tapering ends with secondary thickenings of annular, spiral, scalariform and reticulate types and cell walls are pitted. Trachea are vessels with the tapering ends and their transverse walls are disintegrated, so that cells are placed end to end to form a kind of continuous channels for conducting water and minerals.
Thus, the correct answer is option A.
