Magnetism: separates magnetic materials from non-magnetic. 3rd diagram
evaporation: separates a soluble solid by boiling off. 4th diagram
filtration: separates insolube solid from a liquid. 1st diagram
distillation: separates liquids with different boiling points. 5th diagram

1. two or mor, chemically bonded
2. purify
3. magnetism, evaporation, filtration, distillation, chromatography
Option C: elements produce spectra with only few distinct lines.
The spectra are not continuos and are different for every element. This permits to identify elements.
