Step 1: Understand the key characteristics of a public good. Public goods are defined by two main properties: nonrivalry and nonexcludability.
Step 2: Nonrivalry means that one person's consumption of the good does not reduce the amount available for others. In other words, multiple people can consume the good simultaneously without diminishing its availability.
Step 3: Nonexcludability means that it is difficult or impossible to prevent people who have not paid for the good from consuming it. Access to the good cannot be easily restricted.
Step 4: Compare the options given with these definitions. The correct description of a public good must include both nonrivalry and nonexcludability.
Step 5: Identify the option that states the good is nonrivalrous and nonexcludable, meaning one person's consumption does not reduce others' use and people cannot be easily excluded.
