National defense is the best example of a public good as it is non-excludable (it cannot be denied to anyone) and non-rival (use by one person does not diminish its availability to others). B, fish in the ocean, is also non-excludable, but it is rival as overfishing may lead to depletion of the resource. Bread (A) is rival as consuming one unit means one less unit available for others, and it can be excluded (non-paying customers can be denied access). Scrambled satellite broadcasts (C) are excludable as those who have not paid have limited access, and they are not a public good as they are not non-rival (one person being able to access it does not limit the ability of others to do so).
