Answer: Option (d) is the correct answer.
Step-by-step explanation:
A heterogeneous mixture is defined as the mixture in which solute particles are unevenly distributed into the solvent.
For example, in lasagna particles are not evenly distributed so it 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, graphite, sports dink, fluorine gas and cola all contains evenly distributed solute particles.
So, all of them are homogeneous mixtures.
Thus, we can conclude that out of the given option lasagna is a heterogeneous mixture.
