Which of the following most accurately represents a heterogeneous mixture?
Sand and water solution
A heterogeneous mixture has a non-uniform composition, with the components staying in separate visible phases that can be told apart and separated by simple means such as filtration or settling.
Sand does not dissolve in water; the grains stay as a distinct solid phase that settles out and can be filtered off, so the composition differs from point to point. Sodium chloride, sugar and acetic acid all dissolve to give a single uniform phase, which makes those homogeneous.
Hence, the answer is Sand and water solution.
