Decantantion
5 = F
Filtration is the process a liquid from solid using a porous material. This technique requires a set up and a good porous material eg filter paper.
6 = B
This technique is to separate a mixture of solids by converting them from solid phase to gaseous phase since they sublime.
3 = deposition.
The answer isn't in the option but deposition is the process of substance in gaseous phase to change into solid state without passing through liquid phase. Deposition is the opposite of sublimation.
