Match each operation to its equipment by its single most distinctive keyword. Inversion of soil is the classic job description of the mouldboard plough, so (E) pairs with (V), ruling out options 1 and 2 where (E) is linked to (III) or (II). Soil pulverization needs fine chopping action, which is exactly what a rotavator's rotating blades do, so (C) pairs with (I); this also rules out option 4, which links (C) to (I) but breaks down elsewhere by linking (D) to (V), leaving no equipment for soil inversion. Working through the remaining pairs, cultivator for intercultural operation, sub-soiler for deep ploughing, and strip-till drill for conservation tillage, confirms option 3 is fully consistent. \[\boxed{(A)-(II), (B)-(III), (C)-(I), (D)-(IV), (E)-(V)}\]
