b. Evaporation
c. Sublimation
d. Freezing


ANSWER: See Answer
 
Sublimation is a process when solid changes directly into gas instead of changing into a liquid first. Dry ice is an example of the Sublimation process because it doesn't change into liquid CO2 and directly changes into gaseous CO2 when heated.

Hence, Dry ice is an example of the Sublimation process.
