a. condensation
b. deposition
c. evaporation
d. melting

Explanation:

Sublimation is the process where a solid directly changes into a gas without passing through the liquid state. Iodine changing from a black - solid to a purple gas without becoming a liquid first is an example of sublimation. Condensation is gas to liquid, deposition is gas to solid, evaporation is liquid to gas, and melting is solid to liquid.

Answer:

E. sublimation
