Solution

The correct option is C transpiration pull
The movement of water in the xylem is explained by the cohesion-tension theory. According to this theory, the water moves up in the xylem via the force of transpiration which is created because of the evaporation of water from the leaves of the plant.

So, the correct answer is 'transpiration pull'.
