Answer: B. a lower per capita income. 
Explanation:
Per capita income refers to a measure of economic development that divides a nation's GDP by the population of the country. It is meant to show in theory, the amount of wealth that each person in the country has. 
A developed country like the United States would have a very high GDP which when divided by the population of the U.S. would give a higher per capita income. This is unlike a developing country that would have a lower GDP and by extension, a lower per capita income as well.
