Mercury in free surface means it takes convex shape. So, B is the right answer.

If it's convex means curved upward.

The convexity upward.
The bent portion will be an upside.
So, the curve upward is the right option.

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.

Right answer is Option C.
Because : when adhesion force is less than the cohesion force, liquid gather into droplet. For Ex (Mercury).
Cohesion>Adhesion, Top surface of mercury is convex & mercury fall in the capillary tube.

You are correct but here it is asked curved in which direction which should be curved upwards or convex upwards.
