The term for money invested into production through capital assets is

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

Answer: (D)

Capital refers to the assets that enable production and the funds used to acquire or maintain them. In economics, the factors of production include capital, which means the physical tools and structures—machinery, buildings, equipment, technology—as well as the money invested to obtain and sustain these assets. When money is put into production through these capital assets, you’re engaging in capital investment, which expands a business’s ability to produce goods or services. This distinguishes it from labour (human effort), land (natural resources), or services (performed tasks); none of those describe the assets and funds specifically tied to producing output in the same way.
