Answer:
The correct answer is letter "A": Production increases at a decreasing rate.
Step-by-step explanation:
Law of Diminishing Returns states that the marginal product of an additional employee will be less than the marginal product of a previous employee at some point as the number of new employees increases. Adding additional employees at a certain point will saturate the workplace to the point that there will be workers without being assigned duties. There, productivity begins to decrease gradually.
