Solution
The correct option is B transpiration
In tall trees, the driving force to move water from root to the top is transpiration. During transpiration, as the water evaporates through the stomata in the leaves, it creates a negative pressure in the leaves and tissues of the xylem.
This negative pressure exerts a pulling force on the water in the plant’s xylem and draws the water upward (just like you draw water upward when you suck on a straw).
