   During an expedition across the crystalline steppes of an uncharted exoplanet, a surveyor collects a sample containing coarse insoluble crushed basalt suspended in an aqueous solution of dissolved luminescent mineral salts. To separate the mixture, the surveyor pours it through a funnel lined with porous filter paper into a collection flask. Which of the following statements correctly predicts the behavior of the components and the scientific principle of this separation?

   • A) The dissolved luminescent salts remain trapped on the filter paper because their electrical charge binds them firmly to the paper fibers.
   • B) Both the crushed basalt and the dissolved salts pass completely into the collection flask because filtration can only separate gases from liquids.
   • C) The crushed basalt passes into the collection flask while the dissolved mineral salts collect as residue due to differences in boiling points.
   • D) The crushed basalt is retained on the filter paper as residue because its particles are larger than the pores, while the dissolved salts pass through into the filtrate.
