In the case of a rivalrous good, it can be related to the rivalry between teams, companies, or any entities that compete for the same limited resource or market share.

b. If someone accessing the good prevents someone else from accessing that same good: This concept is at the core of rivalrous goods. In the case of a rivalrous good, when one person consumes or uses it, it diminishes or prevents another person from accessing or using it. This exclusivity and the ability for one person to hinder another's access are important characteristics of rivalrous goods.

c. It's a very competitive good that many people share: A good is considered rivalrous when it is in high demand among many people and there is limited availability or supply. The competitive nature of the good, with multiple individuals or parties vying for it, leads to rivalry and competition for access. The shared desire for the good intensifies the rivalry.

Therefore, when a good exhibits these characteristics, it can be considered a good rivalrous good.
