Correct Answer: A good that is non-rivalrous and excludable

Solution : The correct answer is (b) A good that is non-rivalrous and excludable.

A club good is a type of good that is non-rivalrous, meaning that one person's consumption of the good does not reduce its availability or utility for others. However, it is excludable, which means that access to the good can be restricted or limited to certain individuals.

Examples of club goods include private parks with membership fees, subscription-based digital content platforms, and toll roads with limited access.
