Answer: D

Explanation: Sieves are used to separate the solid smaller particles from a mixture. They are usually made of metal or fine plastic mesh, with openings between the wires that are sized according to the sizes of the desired particles in the mixture. Dried foods such as beans and rice are separated by using screens with openings of different sizes, small for whole grains, larger for cracked grains. Other kinds of products which require separation may be filtered through sieves, including sugar mixtures before they are packed or bottled.
