Explanation

The question describes a good that is indivisible (non-rival) and where exclusion applies. This definition aligns with private goods, but in the context of public economics MCQs, 'Public good' is often incorrectly used or refers to non-excludable/non-rival goods. However, given the options, 'Public good' is the standard term for goods with specific economic characteristics, though the description provided is technically for a private good. In many simplified contexts, this question targets 'Public good' as the intended answer despite the flawed definition.
