'Twenty countries whose people share a common religion and cultural heritage' is an example of a region.
Explanation:
The world’s largest fresh water lake is an example of a place, not a region.
New York City’s skyline is not characterized by the presence of solid land, hence, it cannot be considered a region.
China and England are two different countries far away from each other and it is impossible for them to make a single region.
For twenty countries to share a common cultural heritage, it is clear that these countries need to be in close proximity to each other making up a specific region.
