Concept:Factors of production have specific rewards, and machinery/equipment belong to capital.
Explanation:In production, resources are grouped into land, labour, capital, and entrepreneurship.
Machinery, tools, and equipment are man-made aids to production, so they are classified as capital.
The payment received by the owners of capital for allowing its use in production is called interest.
Profit is the reward for entrepreneurship, not capital.
Rent is the reward for land, and wages are the reward for labour.
Therefore, the reward on machinery and equipment is interest.
Answer:B. Interest.
