Answer: Option (a) is the correct answer.
Explanation:
A mixture in which solute particles are unevenly distributed into the solvent then it is known as a heterogeneous mixture.
For example, salt and sand mixed in water is a heterogeneous mixture.
A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed in a solvent.
A homogeneous mixture is a clear solution.
For example, salt dissolved in water is a homogeneous mixture.
Components of a mixture never combine chemically with each other.
Thus, we can conclude that two heterogeneous mixtures is the best description of what Marie made in the cups.
