What best defines a solution?

• A. A heterogeneous mixture in which the composition varies.
• B. A homogeneous mixture in which one or more substances (solutes) are dissolved in another substance (solvent).
• C. A solution where no solutes are present.
• D. A mixture consisting of a solvent only.

Answer: (B)

A solution is a homogeneous mixture formed when a solute dissolves in a solvent, giving a uniform composition throughout. In a solution, the dissolved particles are dispersed at the molecular level, so the mixture looks the same everywhere and you don’t see separate phases. The solvent is the substance present in the larger amount, while the solute is what gets dissolved. This description matches real-world examples like salt in water or sugar in tea. The other descriptions describe either mixtures with visible, separate parts (not a solution) or a pure solvent with no dissolved substance (also not a solution).
