Solution

The correct option is D (i), (ii), and (iii) only
Conversion of water into vapor is called vaporization.Vaporization occurs when heat is absorbed by the matter.
Conversion of ice into liquid water is called fusion. Fusion occurs when heat is absorbed by the matter.
Conversion of solid CO2 into gaseous CO2 is called sublimation. Sublimation occurs when heat is absorbed by the matter.
Conversion of vapor into liquid water is called condensation. Condensation is the reverse of vaporization i.e. change in the physical state of a substance from a gaseous state to a liquid. Vaporization occurs when heat is absorbed by the matter and condensation occurs when heat is released by the matter.
