The correct answer is A. Remove salt from water.

Explanation

Desalination is the process of removing salt from seawater; this is the opposite of salination that increases the amount of salt in a substance. This means in this process a salty substance is transformed into a purified substance as water is separated from the salt through methods such as pressure, evaporation, condensation, distillation and even refrigeration. Additionally, this process is used to obtain water for human consumption. So, the correct answer is A. Remove salt from water.
