Answer:
B. The reduction of waste
Step-by-step explanation:
Economic theory aims to establish the best ways to produce, distribute and market goods and services through the rational use of available resources. In other words, economic theory always aims to seek efficiency by mapping which is the best way to allocate inputs that will be able to produce a larger amount of products at a lower cost. Thus, part of the productive planning is the mapping of the consumer market, the allocation of inputs and the efficient way of distribution of services. Waste reduction is not a parameter that guides economic decisions directly. This is more part of the scope of environmental science.
