Free surface of a liquid behaves like a sheet and tends to contract to the smallest possible area due to the force of cohesion. The force of cohesion is defined as the force of attraction between molecules of the same substance.

It is Surface tension.

Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are also certain emergent mechanical effects.

What is the difference between Cohesive and adhesive?

What is mean by surface tension?

What is adhesion?

Surface tension might be a better option than cohesive-force.

Cohesive force - it is a type of surface tension.

Cohesive force is nothing but attraction of liquid molecules. So it causes smallest possible area of the liquid.

Cohesive force is partially responsible for this but the major role for this is played by surface tension. Since surface tension is not in the options. So, the right answer will be cohesive force.
