Correct option is B
(A) Electromagnetic Separator: As we know, electromagnetic separators are used to separateferrous metals, so this would align with(III) Ferrous Metals.
(B) Trommel Screen: This equipment is used to separate materials based on their size and density. In this case, it separatesparticulates, so it corresponds to(IV) Particulates.
(C) Air Classifier: This is used to separate materials based on particle size and density, typically separatingheavy and light fractions, so it corresponds to(I) Heavy and light fraction.
(D) Eddy Current Separator: Eddy current separators are used to separatenon-ferrous metals, which means this corresponds to(II) Non-ferrous metals.
