Answer:

probably D. It must undergo an exothermic change

Step-by-step explanation:

because of the definition of exothermic change

-An exothermic phase change releases heat energy into its environment. These changes include freezing and condensation. When a substance loses heat energy, the attractive forces between atoms slow them down, reducing their mobility.

also dry ice is very..very cold -109º F (-79º C),
