Cohesive force is the right one.

Surface tension is correct. I agree.

Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass. When liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.

According to me, Cohesive force is the correct answer. Surface tension is also a reason because of cohesive force b/w surface molecules of mercury.

When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side. Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass. Then what's the correct answer?

Cohesion is correct answer.

I think Cohesion, surface tension is produced by cohesion. Cohesion is attractive force within the same type molecules, of this opposite is adhesion.

Cohesion is absolutely right answer. Forces between mercury is greater than adhesion forces.
