A pure public good is: one that can easily be sold by the unit. one that is nonrival in consumption. one whose benefits are not subject to exclusion. Both (b) and (c) are correct. g

The correct answer is

Both (b) and (c) are correct

Explanation:

A pure public good also called social or collective good, is one that is perfectly non-rivalrous in consumption and is non-excludable.

Non-rivalrous: This means that everyone has access to such goods and the use of these goods by one person does not deplete its availability to the others. An example is a streetlight or a lighthouse.

Non-excludable: A good is non-excludable if non-paying consumers cannot be prevented from having access to their usage. An example is air.
