Answer:
d. Water is transported in the phloem.
Explanation:
Xylem is the vascular tissue responsible for the movement of water and dissolved minerals from roots to various plant parts. Phloem is another vascular tissue that serves mainly in the translocation of sugars. The cohesion-tension model of water transport explains that the upward movement of water from roots to the aerial plant parts is drive by transpiration pull. Transpiration of water from leaves results in a large negative pressure in xylem elements. Cohesion and adhesion properties of water maintain the water column in xylem elements.
