The correct response is:

filtration to collect the sand and distillation to collect the salt

Here's why:

  1. Filtration can be used to separate the sand from the mixture because sand is a solid and will remain as residue on the filter paper, while the saltwater solution will pass through.

  2. Distillation can then be employed to separate the salt from the water. During distillation, the water is heated until it evaporates, leaving the salt behind. The water vapor can then be cooled and condensed back into liquid form, which collects separately.

So, the combination of filtration and distillation is the appropriate method for separating the sand and salt.
