Answer:
The correct answer is b), specialization.
Step-by-step explanation:
The specialization is the focus on a single task instead of covering the entire work process. Therefore each person does the job he knows best without using unnecessary resources.
The division of labor is the form of production where tasks are divided, which are carried out by specialized workers.
The productivity is the ability to produce goods with certain resources. Specialization increases productivity.
The value paradox assesses how the value of goods is determined.
