Answer:
The correct answer is letter "D": The football game you forego by watching the movie again.
Explanation:
Opportunity cost is what a person sacrifices when they choose one option over another. Opportunity cost is calculated by subtracting the return of the forgone option from the return of the chosen option. The result represents what was left on the table. Sometimes the chosen option can provide better returns than the forgone option and vice-versa.
In that case, the opportunity cost of watching "The Dark Knight Rises" one more time with a friend is the football game left behind.
