Answer :
A solution is a homogeneous mixture, where substances are evenly distributed. This means that the components are uniformly spread out at a molecular level throughout the mixture.
Examples of solutions include saltwater, where salt (solute) is dissolved in water (solvent), forming a homogeneous mixture where the salt particles are evenly distributed in the water.
In contrast, a heterogeneous mixture is where substances are unevenly distributed, such as a salad with different ingredients like lettuce, tomatoes, and croutons not evenly mixed throughout.
Therefore, the correct option is: a homogeneous mixture, where substances are evenly distributed.
