D. Technological is not one of the three types of resources. The three types of resources are natural resources, human resources, and capital resources. Natural resources are materials or substances that occur in nature and can be used for economic gain, such as forests, water, minerals, and land. Human resources are the people who provide labor or work to produce goods and services. Capital resources are man-made goods that are used to produce other goods and services, such as machines, tools, and buildings. Technological resources are tools or techniques used to facilitate production or communication, but they are not considered a separate type of resource.
