C. because both water and salt contain small amounts of other substances that combine within the solution

Salt water is classified as a mixture because it is a combination of water and salt, both of which contain small amounts of other substances that create a solution when combined. The salt molecules do not chemically bond with the water molecules, and the chemical and physical properties of sodium chloride and water remain unchanged within the solution.
