Rupture and fractionation of the water column do not occur during the ascent of sap because of:

  1. A
    Transpiration pull
  2. B
    Lignified thick walls
  3. C
    Cohesion and adhesion
  4. D
    Weak gravitational pull

Solution & Step-by-step Explanation

Cohesion (attraction between water molecules) and adhesion (attraction between water and vessel walls) maintain the continuity of the water column under high tension.
