Capillary action of the liquid can be explained on the basis of its ?

Aresistance to flow
Bsurface tension
Correct Answer
Cheat of vaporisation
Drefractive index.

Solution

Capillary action is the movement of liquid in the places like narrow spaces where there is no opposition from external forces. Capillary action takes place because the liquid is sticky. Hence, the cohesive force and adhesive force which is present in liquid is because of surface tension, keeps the liquid bounded.
