Answer: The opportunity cost in this scenario is the three opportunities which Harry lost by making a decision to visit his parents.
Explanation:
Opportunity cost is the loss of an opportunity because of choosing the alternate option. In the following example, we can figure out that during the weekend Harry planned to paint his house, go for a fishing, and attend his friend’s birthday party. But his parents called him for a family dinner. So Harry choose to visit his parents and have dinner with them instead of partying with his friends, completing his painting task, and going for fishing. In this way, Harry lost three opportunities.
