Which of these mixtures could be most easily separated by filtration ?

Filtration is used to separate a solid from a liquid in which it is suspended. Filtration is also used to separate a substance from a mixture because one is insoluble in the solvent and the other is soluble. The separation is due to particle size.

Explanation:

Filtration is a separation procedure where a mixture is gone through a filter that permits one segment to go through uninhibited yet hinders another segment from going through.   We can utilize filtration to isolate a mixture of a solid in a fluid or a solid in a gas.   When all is said in done this technique sorts by size, with the filter going about as a barrier that permits littler particles to experience, however, holds bigger particles back.   Filtration works best when the solute isn't dissolved in the solvent. For example, sand and water can be separated through filtration as the two mixes don't dissolve up with one another. In any case, sugar and water would not be separated through filtration as they break down with one another.
