The greatest number of Internet users are in which combination of regions?

• A. Australia, North America, and Europe
• B. South America, Asia, and North America
• C. North America, Asia, and Europe
• D. South America, Asia, and Europe

Answer: (C)

Asia has by far the largest number of Internet users due to its huge population, so the trio that yields the highest total should include Asia plus the next two regions with the largest user bases. Among the options, Asia with Europe and North America adds up to the most users, because Europe and North America each have substantial user counts, more than South America does. Replacing either Europe or North America with South America lowers the total, since South America has fewer Internet users than those regions. So the combination of Asia, Europe, and North America has the greatest number of Internet users.
