The correct answer is option C, that is, cohesion and adhesion.
The molecules of water stay near to each other via cohesion, that is, the combined activity of hydrogen bonds amongst the molecules of water. The property of cohesion assists the plant to move water upwards from the root via the xylem towards the leaf.
At the same time, adhesion between the molecules of water to the cell walls of the plant assists to counteract gravity while water is conducted from the roots to the leaves. Thus, both the cohesion and the adhesion produces a capillary action, which keeps the molecules of water interacting with each other and conducting via the plants out to the cells of the leaf.
