Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass.

@Meet.
Cohesion, adhesion, and surface tension are properties of capillarity. But the answer should be Cohesion.
Cohesion, adhesion, and surface tension are properties of capillarity. But the answer should be Cohesion.

The surface tension is due to cohesion only and in question 'PROPERTY OF FLUID' (cohesion is FORCE)is asked. So the answer is surface tension.

As the cohesion is more than the adhesion so it doesn't wet the glass.
Angle of contact is obtuse.
Angle of contact is obtuse.

Surface tension is binary property Adhesion and cohesion. But main reason is cohesion behind it.

As per my opinion, the correct answer, Cohesion and Surface Tension: Both Option are correct.

You are right @Sharad.
Surface tension is only due to cohesive property of fluid.
Surface tension is only due to cohesive property of fluid.
