Answer:
Solution
Explanation:
A solution is generally defined as an homogeneous mixture.
What this means is that it has only a single phase.
A solution is generally formed as a result of a solute coming in contact with a solvent.
The solvent is the liquid while the solute is the solid. It is the solute that is dissolved in a solvent.
When a solution is thus formed from the interaction between the two , an homogeneous phase is formed.
Kindly note that all other options in the question are of 2 phases and thus are heterogeneous
