The opportunity cost of watching a movie will be equal to
A) Time lost while watching the show
B) The pleasure that could have been enjoyed watching TV instead
C)The pleasure enjoyed by watching the show
D) Amt paid to buy the ticket

Dear Student, Opportunity cost is whatever you could have done instead. If the movie you watched played at the same time as your kid’s little league game, it cost you watching the game to see the movie. The opportunity cost would be the same even if you had actually paid for the movie ticket. So it's all depends upon your priorities.
But if it is measured in terms of money then you should go for the option (d) because instead of buying that movie ticket you can buy your favorite food which provides you more utilities.
