(B) Water moves through the xylem vessels and tracheids of roots, stems, and leaves primarily via $Bulk \text{ } flow$ (also known as mass flow). This movement occurs due to the pressure difference created by transpiration pull, which pulls the water column upward as a single unit from the roots to the leaves.
