Mercury is highly cohesive so it has a very high force of attraction between similar molecules. So mercury doesn't wet the glass.

I think Cohesion is the correct answer.

The correct answer is Cohesion.

Surface tension is a property that arises due to the intermolecular forces of attraction among the molecules of the liquid. In the case of mercury taken in a glass tube, adhesive forces are weaker than cohesive forces. So, the mercury molecule does not wet the glass.

Yes, Adhesive forces are right.

Cohesive forces between molecules cause the surface of a liquid to contract to the smallest possible surface area. This general effect is called surface tension.

So, option A right.

Mercury does not wet the glass because the cohesive force with the drops is stronger than the adhesive force between the drops and glass.

Adhesive forces are right.

Cohesive force is the right one.

Surface tension is correct. I agree.
