Your answer: —  Â·  Correct: D
Explanation

Opportunity cost is a fundamental economic principle defined as the value of the next best alternative that is sacrificed when a choice is made [1]. It represents the gain foregone from the second-best activity rather than the sum of all possible alternatives [3]. For instance, if an individual chooses to invest money in a family business, the opportunity cost is the maximum benefit they could have received from the single best alternative use of that money, such as interest from a specific bank deposit [3]. While economic costs include both direct out-of-pocket expenses and opportunity costs, the opportunity cost itself specifically refers to the potential benefits missed from the next best option [2]. This concept highlights the trade-offs inherent in resource allocation for individuals, businesses, and governments [3].
