I think it should be option B, because cohesion is more than adhesion, same as a case in water.

B is the correct.
Curved Upward because mercury has a high cohesive value than adhesion.
Curved Upward because mercury has a high cohesive value than adhesion.

Wrong. Because of cohesive force is predominant here than adhesive force.

The fluid falls down due to strong cohesion but its shape is curved downwards. So the answer is B.

Curve upward. Heavy liquid and water downward cover.

C is correct.
Because in the case of mercury medium cohesive force between molecules is greater than adhesive force and capillary fall occurs.
So C is correct.
Because in the case of mercury medium cohesive force between molecules is greater than adhesive force and capillary fall occurs.
So C is correct.

Because mercury is also a type of liquid, and the plane of all liquids segment (move downward) due to surface tension force in open tubes.

I think answer B is correct.
Because cohesion property is more than the adhesive property.
Because cohesion property is more than the adhesive property.

Curve is upward due to dominant force is cohesion in mercury. While downward in water, in which dominant is adhesion.
