Answer: Option 2

For almost all the gases the maximum inversion temperature is above the room temperature but for gases like $${H_2}.$$ The inversion temperatures are 200K and 24K respectively so by throttling always heating occurs to accomplish cooling they are brought below the inversion temperature by some medium like liquid nitrogen etc. Hence to cool the $${H_2}$$ simply throttling wont suffise.

If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that?
