Which of the following goods is both nonrival and nonexcludable?

A tuna in the ocean

A hot dog at a hot dog stand

The light from a lighthouse at a harbor entrance

A soccer match in a stadium

Answer: The light from a lighthouse at a harbor entrance

Explanation:

Non-rival and non-excludable commodities lie under Pure Public Goods which means that consumption of these goods by an individual doesn't change the supply or demand for other individuals i. e. non-rival and the individual is not excluded from the consumption of this good. Hence, the light from a lighthouse is non-rivalrous and non-excludable.
