Final answer:
It is false that service providers only offer services and manufacturers only offer products; many firms offer a combination of both to satisfy customer needs.
Step-by-step explanation:
The statement that at the level of the firm, service providers offer just services and manufacturers offer just products is false. Today, many firms operate in a gray area where they offer both products and services to meet the needs of their customers. For example, a manufacturer may also provide installation, maintenance, or training services for their products. Similarly, service providers such as software companies often bundle physical products with their service offerings. The lines between products and services have become increasingly blurred in modern economies.
At the level of the firm, service providers can offer both services and products. For example, a company like Apple offers both iPhones (products) and Apple Care (a service). On the other hand, manufacturers can also offer services along with their products. For instance, a car manufacturer may also provide car maintenance services.
