Answer:
D) sightseeing
Explanation:
Opportunity cost also known as the alternative forgone, can be defined as the value, profit or benefits given up by an individual or organization in order to choose or acquire something deemed significant at the time.
Simply stated, it is the cost of not enjoying the benefits, profits or value associated with the alternative forgone or best alternative choice available.
For instance, if you decide to invest resources such as money in a food business (restaurant), your opportunity cost would be the profits you could have earned if you had invested the same amount of resources in a salon business or any other business as the case may be.
In this scenario, the opportunity cost for Mikael is sightseeing to the popular Oura Preta during his stay in Brazil.
Thus, the alternative forgone by Mikael is a visit to the popular Oura Preta i.e sightseeing while retaining or maintaining other expenses such as food, hotel reservation, and transportation.
