Which of the following is an example of derived demand?

Labor is an example of derived demand. Derived demand refers to the demand for a good or service that arises as a result of the demand for another good or service. In the case of labor, the demand for workers is derived from the demand for the goods or services that those workers help produce. For example, if a company sees an increase in demand for its products, it may need to hire more workers to meet that demand. Conversely, if demand for a company's products decreases, it may need to lay off workers. The demand for labor is therefore derived from the demand for the company's products. In contrast, tax relief, wage increase, and entertainment are not examples of derived demand. Tax relief is a form of government policy, wage increase is a labor market condition, and entertainment is a consumer good that is demanded directly by individuals.
