Moves water UP
A
Xylem
B
Phloem
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Capillary action draws water up within the xylem. Cohesion-tension pulls water up the xylem.

Detailed explanation-2: -The vascular tissues of these plants are called xylem and phloem. The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots (where they are taken in) to the rest of the plant.

Detailed explanation-3: -The suction force (negative pressure) created by transpiration from the leaves’ surface draws water from the soil and roots through the xylem. Water is sucked up as a result of the xylem vessel. Due to the appearance of capillary action, transpirational pull moves water from roots to leaves.
