Solution

The correct option is C A is true but R is false
Decreasing temperature decreases the spaces between the particles of matter.
A gas can be liquefied by reducing its interparticle spaces. Therefore, a gas can be liquefied by decreasing its temperature.

Therefore, A is true but R is false.
