The public good among the options provided is **national defense**. Public goods are characterized by being non-excludable and non-rivalrous, meaning that they are available for everyone to use, and one person's use does not diminish another person's ability to use it. National defense fits this definition, as it protects all citizens without reducing the level of protection available to others.
In contrast, college education, textbooks, and stock portfolios have particular constraints and are not considered public goods.
