Concept:The implement shown is a harrow, which is mainly used after ploughing to prepare a fine seedbed.
Explanation:During ploughing, large soil clods and lumps are turned up.
To prepare the land for planting, these clods must be crushed and broken into smaller, finer particles.
A harrow performs this job by passing over the ploughed field and breaking the clods.
It also helps to level the soil surface, but its primary function is not to remove or turn over soil, nor to cut stumps.
Removing soil, turning soil, and cutting stumps are done by other implements.
Therefore, the most accurate description of the harrow’s function is breaking clods.
Answer:C. break clods
