Option B is correct.When a solution of sand and aqeous sodium chloride is filtered, the sodium chloride dissolves and passes through the filter paper as the filtrate while the sand remains on the filter paper as the residue.

Filtratn ix used 4 seperatn solubl nd insolubl substancz,since nacl ix soluble in aqueous form,itz only an insolubl substance(sand) dat can b seperatd frm nacl wen both ar in d xame solutn
  • cyberformz: Filtratn z used to seperarte soluble substance frm insoluble substance . Since NaCl z soluble in water, starch wc z insoluble cn b used also bt in tink d really ansa z sand cos sand those nt contain hydrogen bond while starch contain contain hydrogen bond so et cn dissolve in water bt nt in all proportn
