Which of the following best fits the economic concept of "the law of diminishing marginal returns" in production? Group of answer choices A pizza company needs to increase production so they hire three additional people. The first worker hired is skilled and hardworking, and increases output the most.

Hiring more workers helps to get a bit more output but it begins to get crowded in the pizza kitchen which decreases productivity of additional workers.
