Mixtures are physical combinations of substances and can be separated by physical methods like filtration, evaporation etc. Compounds are chemically - bonded substances and require chemical methods for separation. The first option is wrong as mixtures are physically combined. The second option is wrong as compounds are chemically formed. The fourth option is wrong as compounds need chemical processes for separation, not just filtration which is a physical method.

Answer:

Mixtures can be separated into their components by physical means.
