Analyze the following gross national income (GNI) numbers and the country populations to select the country that has the highest GNI per capita

Country D: GNI US$2,000 and population of 200

Country C: GNI of US$10,000 and population of 1,000

Country B: GNI of US$US4,500 and population of 200

Country A: GNI of US$3,900 and population of 80

To determine the country with the highest Gross National Income (GNI) per capita, we need to calculate the GNI per person in each country.

For Country D:
GNI per capita = GNI / population = $2,000 / 200 = $10

For Country C:
GNI per capita = GNI / population = $10,000 / 1,000 = $10

For Country B:
GNI per capita = GNI / population = $4,500 / 200 = $22.5

For Country A:
GNI per capita = GNI / population = $3,900 / 80 = $48.75

Based on the calculations, we can see that Country A has the highest GNI per capita of $48.75. Therefore, Country A is the country with the highest GNI per capita among the given options.
