Concept:The implement part that runs horizontally beneath the soil surface and slices weed roots is the share or sweep blade.
Explanation:In the illustration, the part that makes horizontal cuts into the soil is the blade attached below the frame of the implement.
This blade is designed to move just under the surface, cutting through weed stems and roots as the implement is pulled forward.
By slicing horizontally, it loosens the soil and uproots weeds without requiring deep ploughing.
The other labelled parts, such as the frame, handles, and wheels, only provide support, balance, or direction and do not perform the actual cutting action.
Since the typical farm implement for weed control has its cutting share labelled as II in the diagram, this part matches the function described in the question.
Answer:II (Option B)
