Answer:
B) higher, because more games are televised today.
Explanation:
Opportunity costs are the cost of choosing one alternative from another.
In this case, when college students attend college football games they are unable to do other activities while they are at the stadium or going to the stadium. The cost of those alternatives that are lost are higher now because many college football games are televised. So a student is now able to watch the game while doing other activities.
