Solution

The correct option is A Transpiration
Water is pulled upwards through the plants due to transpiration. Transpiration is the loss of water in the form of water vapour through stomata. The model that explains this translocation of water is called Cohesion-tension transpiration pull model of water transport. Less than one percent of water reaching the plant is used in photosynthesis and plant growth.
Hence, the correct answer is'Transpiration'.
