Explanation The GDP is the Gross Domestic Product of the economy. As the name suggests, it is the money value of all the final goods and services produced within a country's political boundary in a given period of time, which is usually one financial year. It includes the money value of all the final goods and services only. The GDP per capita can be calculated by dividing the GDP with the total population as follows: GDP per capita = GDP of the country Total Population of the country The developed countries are the countries that have the industrial sector developed much faster and better than the other countries. They will have higher rates of economic growth and development and higher per capita GDP. The less developed countries are those countries that have lower levels of industrial growth and economic development. Option (e): The GDP per capita is the share of GDP per head in the economy. It can be easily calculated by dividing the total GDP with the total population in the economy. However, the main issue is that the population in Less Developed Countries will be much higher than the Industrially Advanced Countries leading to unequal comparison between them. Thus, the LDC classification itself is of the questionable accuracy. In addition, the data will be subject to greater errors for LDC compared to the IACs. The GDP per capita per nations will be misleading due to the fact that it will not be able to point the income distribution in the economy thus, failing to show the income inequality in the economy. In addition, the fluctuations in the exchange rates in the exchange markets also cause the GDP calculations to change. Thus, all the given answers are correct as problems in comparing the GDP per capita between nations because the GDP per capita does not account for the difference in the cost of living among the different nations. Thus, option 'e' is correct. Option (a): The classification of countries as Less Developed Countries is on the basis of the economic growth and development and the improvement in the industrial sector is being debated between the economists. This means that the LDC classification itself is subject to questionable accuracy
