A. factors that are used to make goods and services
Explanation:
Productive resources are the items used in the production process of a product, such as machinery and equipment. Companies buy these resources from their suppliers and use them to turn the inputs into a manufacture to sell. For example, for the manufacture of a shoe, machinery is considered a productive resource as it is in the machine that the shoe will be made. Leather is the input and the shoe is the final product.
