Solution

The correct option is A Filtration followed by crystallisation
Filtration uses a filter paper or fine porous ceramic to separate an insoluble solid from a liquid. Thus, insoluble barium sulfate solid will be separated from the mixer of the solution by filtration.
Now, soluble copper sulfate from the filtrate solution can be separated by the process of crystallisation.
