Answer: The correct option is B.
NaSO4 and SrSO4.
The B option is not complete, 4 is not added to it.
Explanation:
FILTRATION is a process where solid particles from a liquid mixture are removed or separated from it using a filter medium like filter paper, flask and funnel.
The solid can be removed because they are not soluble in the liquid suspension.
From the question, SrSO4 is poorly soluble in water it is the reason why filtration is used. It becomes the filtrate because it is insoluble in water while NaSO4 is soluble in water.
