Concept:The reward for capital is the income paid to the owner of capital for its use in production.
Explanation:The factors of production include land, labour, capital and entrepreneurship.
Each factor receives its own distinct reward.
Land earns rent.
Labour earns wages or salary.
Capital refers to man-made assets such as machinery, tools, buildings, vehicles and money used to produce goods and services.
The payment made for using such capital is called interest.
This interest compensates the owner of capital for the opportunity cost of lending or investing those assets.
Entrepreneurship earns profit as its reward, while risk is not a payment but a burden borne during production.
Therefore, among the options given, the correct reward for capital is interest.
Answer:A. Interest
