A public good is non-excludable (you cannot prevent people from using it) and non-rivalrous (one person’s use doesn’t reduce another’s).
Answer: national defense — it is non-excludable and non-rivalrous.
The others are private (or club) goods: textbooks and college education are excludable (access can be restricted) and generally rivalrous (limited seats/copies), and a stock portfolio is a private good.
