Answer:
C. hunting in a public game area.
Step-by-step explanation:
A nonexclusive good is one that cannot be possessed Soley by one person, but is used by many people. While exclusive goods are used only by one person. For example if a person buys a car he can restrict it's use to only himself so it is an exclusive good.
A rival good is one whose use affects the rate of use by others. For example at a gas station the petrol bought by one person reduces the amount another can buy.
Hunting in a public game arena is an example of a nonexclusive but rival good.
The game arena is open to everyone, but when a hunter kills game it reduces the number of game other hunters can kill.
