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

Country A: GNI of US$3,900 and population of 80
Country B: GNI of US$4,500 and population of 200
Country C: GNI of US$10,000 and population of 1,000
Country D: GNI US$2,000 and population of 200

To determine the country with the highest GNI per capita, we need to calculate the GNI per capita for each country. GNI per capita is calculated by dividing the GNI by the population.

Country A: GNI per capita = 3,900 / 80 = US$48.75
Country B: GNI per capita = 4,500 / 200 = US$22.50
Country C: GNI per capita = 10,000 / 1,000 = US$10.00
Country D: GNI per capita = 2,000 / 200 = US$10.00

Analyzing the GNI per capita for each country, we find that Country A has the highest GNI per capita at US$48.75. Therefore, Country A is the country with the highest GNI per capita among the options provided.
