Concept:Transpiration pull is the main force that causes water to rise in tall trees.Explanation:Water evaporates from the leaves through stomata during transpiration.This evaporation creates a strong suction force at the top of the plant.The suction pulls water upward through the xylem vessels from the roots to the leaves.This pulling force is called transpiration pull.Cohesive and adhesive forces also help maintain the water column, but the main driving force is transpiration pull.Answer:B. transpiration pull
