Development by highest GDP per capita Steps:

• Assume first number is total GDP (in billions), second is population (in millions).
• Calculate GDP per capita: divide GDP by population for each option.
• A: 600 / 3 = 200
• B: 12000 / 40 = 300
• C: 7000 / 40 = 175
• D: 15000 / 100 = 150 Why B is correct:
• B has the highest GDP per capita (300), the standard measure of economic development per person. Why the others are wrong:
• A: Lowest per capita (200), indicating underdevelopment.
• C: Low per capita (175) despite moderate GDP.
• D: High GDP but diluted by large population, yielding low per capita (150).

Final answer: B
