What would be considered a public good a cartoon-themed amusement park Yellowstone National Park a membership-only country club a shopping mall?

A public good is typically characterized by being non-excludable and non-rivalrous, meaning that it is accessible to everyone and its use by one person does not diminish its availability to others. Among the options provided, Yellowstone National Park qualifies as a public good, as it is open to the public for recreation and enjoyment without restricting access based on membership or payment. In contrast, a cartoon-themed amusement park, a membership-only country club, and a shopping mall are all excludable and typically require payment or membership for access.
