The correct answer is B) Transport of water and solutes.
Xylem is the primary tissue in vascular plants responsible for transporting water and dissolved mineral nutrients (solutes) from the roots upwards to the rest of the plant, including the leaves. If the xylem is mechanically blocked, this upward movement of both water and solutes will be significantly impaired.
