What are the properties of solids? Of liquids? Of gases?

Hope this helps.

Gas: assumes the shape and volume of its container particles can move past one another, compressible, lots of free space between particles.

Liquid: assumes the shape of the part of the container which it occupies particles can move/slide past one another, not easily compressible, little free space between particle.

Solid: retains a fixed volume and shape, rigid - particles locked into place, not easily compressible, little free space between particles.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
