    B Adhesion and cohesion Correct Answer Incorrect Answer
    C Surface tension Correct Answer Incorrect Answer
    D Buoyancy Correct Answer Incorrect Answer

    Solution

    The rise of a liquid in a capillary tube is due to surface tension, which pulls the liquid upward against gravity. Adhesion between the liquid and the tube walls also plays a role.
