Answer
The correct option is The process of removing salt from water. This answer is correct because it matches the approved learning objective to describe desalination as a method for obtaining potable water from salty water or sea water in the subtopic Potable water.
Explanation
The correct option is The process of removing salt from water. The process of removing salt from water is correct because it directly supports the approved learning objective to describe desalination as a method for obtaining potable water from salty water or sea water. This belongs to the subtopic Potable water within Using the Earth's resources and obtaining potable water, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Potable water.
Common mistake
Confusing Desalination with Filtration
Students often confuse desalination with filtration, thinking both processes are the same for obtaining potable water.
Understand that desalination specifically refers to the removal of salt from salty water or sea water, while filtration is a separate process that removes impurities from water.
