If a liquid does not wet the surface,its angle of contact is acute or obtuse?

The liquid (mercury) meniscus in a capillary tube will be convex if the angle of contact is

The liquid meniscus in a capillary tube will be convex,if the angle of contact is

The wettability of a surface by a liquid depends primarily on

The parts of motor cars are polished by chromium because the angle of contact between water and chromium 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.
