Solution

The correct option is D Filtration
Filtration is a method that can be used to separate a solid-liquid mixture wherein the solid particles are undissolved in the liquid.
Chalk powder is insoluble in water. When the mixture is passed through filter paper, chalk powder will get collected on filter paper. While water will pass through and can be collected in a container.
Thus, the components can be separated by filtration.
