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

What is the nature of the meniscus for a liquid with an angle of contact of $0^{\circ}$?

$A$ capillary tube is dipped vertically in a liquid. If the liquid surface is hemispherical,then the angle of contact $\theta$ is

Given below are two statements: One is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: Clothes containing oil or grease stains cannot be cleaned by water wash.
Reason $(R)$: Because the angle of contact between the oil/grease and water is obtuse.
In the light of the above statements,choose the correct answer from the options given below.

If the surface of a liquid is plane,then the angle of contact of the liquid with the walls of the container is

Consider a spherical body,one third of its volume is filled with a liquid which has a contact angle of zero with the surface of the sphere. If this sphere (along with the liquid) is taken to gravity-free space,then the shape of the liquid inside the sphere will look like:
