i think is B that is sea water because it is a mixture of salt that is NaCl and water that is H2O and ca be separated by boiling which is a physical change and that is how our common salt NaCl is gotten from.

Sea-water is a mixture because it contains water and various dissolved salts (like NaCl, MgCl2 etc.) in varying proportions - it's a homogeneous mixture

The others are pure substances:
Granulated sugar = sucrose (compound)
Sodium chloride = NaCl (compound)
Iron filings = Fe (element)
