In which of the three states of matter are the particles moving at the greatest speed?

Gas(this is because we are only considering that there are 3 states of matter, while in reality there are 5.)

Explanation:

There are actually 4 states of matter excluding a 5th one that has just been discovered, but if we consider that there are only 3 states of matter then the particles move the fastest in gases. As the particles are the furthest apart.

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
