What does the term "opportunity cost" refer to?

The term "opportunity cost" refers specifically to the loss of potential gain from other alternatives when one alternative is chosen. This concept is rooted in the idea that when you make a decision to pursue one option over others, you forgo the benefits or gains that you could have achieved from those other options.

For example, if an individual chooses to invest time in a particular project instead of working extra hours at their job, the opportunity cost is the income they would have earned during those hours. Thus, opportunity cost emphasizes the importance of considering what is sacrificed when making choices, making it a crucial concept in economics and business decision-making.

In contrast, the other choices do not accurately capture the essence of opportunity cost. The total cost of production focuses on the expenses associated with creating goods or services. The gain from other alternatives does not reflect the concept of loss associated with choice. Lastly, the overall financial investment in a company pertains to funding and capital structure, which is unrelated to the notion of forgoing benefits from alternative choices.
