Question

c. beaker and watch glass
rewatch

Explanation:

Filter paper in a funnel is used to separate solid - liquid mixtures by filtration. Sand is a solid and water is a liquid. The funnel holds the filter paper and allows the liquid (water) to pass through while retaining the solid (sand). Other options like graduated cylinder and beaker are for measuring and holding liquids, erlenmeyer flask and funnel without filter paper won't filter, and beaker and watch glass are not for filtration.

Answer:

d. funnel and filter paper
