Which would be considered a public good? yellowstone national park a cartoon-themed amusement park a membership-only country club a shopping mall?

I believe the answer is Yellowstone national park,
From the options above, only Yellowstone national park fulfill two main criterias for a public goods:
- It must be bought and maintain using the budget that allocated from taxpayers
- It was created for Public use.
All other options are all considered privately owned properties.

You could solve them by trying something new that everyone can agree on or make a decision too.
