$A$ liquid wets a solid completely. The meniscus of the liquid in a sufficiently long tube is

Given below are two statements:
Statement-$I$: When a capillary tube is dipped into a liquid,the liquid neither rises nor falls in the capillary. The contact angle may be $0^{\circ}$.
Statement-$II$: The contact angle between a solid and a liquid is a property of the material of the solid and liquid as well.
In the light of the above statements,choose the correct answer from the options given below.

The meniscus of mercury in the capillary tube is

If a water drop is kept between two glass plates,then its shape is

The wettability of a surface by a liquid depends primarily on

The angle of contact between glass and mercury is......... $^o$
