Answer:
B. North America and Europe
Step-by-step explanation:
The world is not equal everywhere when it comes to development. Some regions are much more developed than others, and the differences in some cases are extremely large.
The most developed regions, or rather continents, are Europe and North America. These two continents, in general, are highly industrialized. Gradually the focus has been moving toward the tertiary and quaternary economic sectors. The people have medium to very high standard, depending on the country, and in general they are democratic societies.
This can not be said about other continents, such as Africa and Asia for example. While Asia has some countries that are economic giants, the majority of the countries in it are not, and some are some of the worst places for living in the world. This can also be said for Africa too, just that in Africa there isn't a single highly developed country, but instead all of them are below average, or in terrible conditions.
