I don’t see the list of substances you mean — please paste the options.
Meanwhile, the general rule: filtration is used to separate an insoluble (or not dissolved) solid from a liquid (a heterogeneous mixture). Good examples: sand in water, chalk (CaCO3) in water, coffee grounds in brewed coffee.
Not separable by simple filtration: dissolved solids in a liquid (salt in water), miscible liquids (ethanol + water), or very fine colloids (which pass through ordinary filter paper). If you give the specific choices I’ll pick the best one.
