The quantity of goods and services produced by one worker or by one hour of work.

• A. Productivity Rate
• B. Efficiency of Labor
• C. Labor Productivity
• D. Output Per Worker

Answer: (C)

The main idea is measuring how much is produced for each unit of labor input, either per worker or per hour worked. This is called labor productivity: total output divided by the amount of labor used (number of workers or total hours). It shows how effectively labor is turned into goods and services.

Choosing labor productivity as the term fits because it directly captures output per unit of labor input, and can be expressed as units per worker or units per hour. The other phrases are less precise or not standard terminology in this context: “output per worker” describes the same idea but is a more limited phrasing, and the others aren’t the conventional label for this measure.
