(B) The xylem tissue in flowering plants is composed of four types of elements: Tracheids,Vessels,Xylem parenchyma,and Xylem fibers.$1$. Tracheids: These are elongated,tube-like cells with thick,lignified walls and tapering ends. They are the primary water-conducting elements in gymnosperms and are also present in angiosperms.$2$. Vessels: These are long,cylindrical,tube-like structures made up of many cells called vessel members. They are the main water-conducting elements in angiosperms.$3$. Xylem parenchyma: These are living cells that store food materials (starch or fat) and assist in the short-distance transport of water.$4$. Xylem fibers: These are highly thickened,dead cells that provide mechanical support to the plant.Out of these,Tracheids and Vessels are the primary elements responsible for the long-distance conduction of water. Therefore,there are $2$ such structures.

How many of the following structures are associated with the conduction of water?
Tracheids,Xylem parenchyma,Xylem fibers,Vessels
