The average kinetic energy of the particles in a sample of matter at 600 K is as the average kinetic energy of the
particles in another sample at -73°C.

answer; ///(d) the correct answer is double or triple

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

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
