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

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.

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.
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.
