Solution
The correct option is D None of the above
As the temperature increases then the vibrational kinetic energy of the molecules increases and molecules overcome the force of attraction between adjacent molecules and this increases the intermolecular distance between them and hence solid CO2 converts to vapours (Sublimation). The decrease in pressure will lead to an increase in intermolecular spaces between molecules and hence solid CO2 converts to vapours (Sublimation).
