Which of the following is a solution?
muddy water
ranch salad dressing
brewed coffee

brewed coffee

Explanation:A solution is a homogeneous mixture of two or more substances. A solution must have a solute ( a substance that can be dissolved or a soluble substance) and a solvent (a substance, mostly liquid , that can dissolve another substance)

For a substance to be dissolved it depends on its degree of solubility.

For our example coffee beans (solutes) are dissolved in hot water which is a solvent and it becomes a homogeneous mixture which is a brewed coffee ; in which you can no longer separate a solute from a solvent. A solution is in one phase which can be either liquid or solid or gas , one can't see any particles in a solution with their makes eyes.
