Solution
The correct options are
A Solvent extraction
B Sublimation
C Magnetic separation
Napthalene can be dissolved in a solvent like benzene and filtered from iron filings. On evaporating the solution napthalene can be obtained back. This method is solvent extraction.
Iron filings can be attracted towards magnet and separated from napthalene. Therefore, method can be used magnetic separation.
Napthalene has the property of sublimation hence on heating napthalene sublimes and gets separated from iron filings by the method of sublimation.
