Which of the following is not a factor of production?

• A. Land
• B. Labour
• C. Capital
• D. Money

Answer: (D)

In economics, factors of production are the inputs that directly contribute to making goods and services: land provides natural resources, labour is the human effort, and capital covers the tools, machinery, and buildings used in production. Money, while essential for purchasing resources and paying for inputs, isn’t itself used to produce output. It doesn’t transform inputs into goods and services, so it’s not considered a factor of production. The other three—land, labour, and capital—do fit that role.
