The plants lose water through their leave by the process called transpiration. The loss of water causes water to move into the plant's roots. Thus, option B is correct.
What is transpiration?
Transpiration is the mechanism by which the plants lose their water through their stomatal pore to the atmosphere. It is best in summers to cool down the temperature of the plants.
The water from the roots, leaves, and stems is forced upwards to the leaves through the openings resulting in cooling. The process of transpiration in leaves is due to the Cohesion-Tension (C-T) mechanism.
This loss of water is beneficial as it goes into the atmosphere again through the water cycle and enters the root system of the plants.
Therefore, option B. the lost water causes the water to move into the roots again is correct.
