The correct answer is B) creating goods and services.
One of the main questions of economics involves deciding upon the method for creating goods and services.
When humans have faced scarcity, they had to make decisions. Economics study this situation and how humans make personal, family, or corporate decisions when they are facing scarcity. Humans need to create efficient ways to create goods and services knowing that people are always demanding the coverage of basic necessities such as shelter and food. The demand for products and services exceeds the available resources. That is when humans have to find the best way to produce and use the resources available.
