B cream on milk
C С water on top of the syrup in a cooldrink mixture

D a plank floating on water

Explanation:

Its not a mixture

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
