Correct Answer: C সঠিক উত্তর: C

Explanation ব্যাখ্যা

The cohesion-tension theory explains how water is transported upwards in plants, primarily driven by the process of transpiration. Transpiration is the evaporation of water from the leaves, which creates a negative pressure that pulls water up the xylem vessels from the roots. This upward pull is due to the cohesive forces between water molecules (causing them to stick together) and the adhesive forces between water molecules and the xylem vessel walls.
