Final answer:
Computer hardware and software technology, robots used in manufacturing, and automated warehouses are examples of physical resources (option B)
Step-by-step explanation:
Computer hardware, robots, and automated warehouses are categorized as physical resources, encompassing the equipment and infrastructure used in production that contributes to increased output and efficiency. Physical resources or physical capital include tangible items such as plant equipment, machinery, and infrastructure that firms use in production. These resources increase productivity in two ways: by increasing the quantity of physical capital and by enhancing the quality of physical capital, meaning the resources become more advanced or efficient.
Human capital, on the other hand, involves the accumulative skills and knowledge that workers possess, which makes them productive. It's important to note that human capital and physical capital often work together, as skilled workers can better operate advanced technology, and new technologies often require these workers to gain further training. Therefore, for optimum economic growth and productivity, a balance of human capital, physical capital, and technological innovation is crucial.
