    D)  adhesion force

    Correct Answer: D

    Solution :

    The force between walls and water called'           adhesion force.             Diffusion of water from its pure or dilute solution into a stronger solution when the two are separated by a semi-permeable membrane is termed as osmosis. In plants water supply is due to osmosis.             The absorption of water by the solid particles of   an adsorbant without forming a solution is called             imbibition.             The loss of water in the form of liquid droplets      from the leaves and other parts of an uninjured or          intact plant is called guttation.
