Why does the temperature of the gas between galaxies in galaxy clusters tell us about the mass of the cluster?

• A)Temperature is always directly related to mass, which is why massive objects are always hotter than less massive objects.
• B)The temperature of the gas tells us the gas density, so we can use the density to determine the cluster's mass.
• C)The temperature tells us the average speeds of the gas particles, which are held in the cluster by gravity, so we can use these speeds to determine the cluster mass.
• D)The question is nonsense-gas temperature cannot possibly tell us anything about mass.
