The correct option is C Root pressure
Root pressure is the force which pushes water through xylem when soil moisture content is high. It is usually high at night in the absence of transpiration. This results in the accumulation of water in the form of water droplets on the edge of leaves of grasses or small plants. It is not visible in tall plants as root pressure is not enough to push water to such heights. This should not be confused with “dew drops ”.
Transpiration is the process where plants absorb water through the roots and then give off water vapour through pores in their leaves.
Osmosis is the movement of water or other solvents through a plasma membrane from a region of low solute concentration to a region of high solute concentration. Diffusion is a movement of particles from an area of high concentration to an area of low concentration.
