(N/A) $\Rightarrow$ Cohesion Force: This refers to the mutual attraction between water molecules,which helps in maintaining a continuous water column in the xylem.
$\Rightarrow$ Adhesion Force: This is the attraction of water molecules to polar surfaces,such as the inner walls of tracheary elements (tracheids and vessels),which helps in resisting the pull of gravity.
$\Rightarrow$ Surface Tension: This occurs because water molecules are attracted to each other in the liquid phase more strongly than to water molecules in the gas phase,which explains the high tensile strength of water.
