Correct Option: A

When economic development takes place specialisation increases. Economic development typically involves improvements in a variety of indicators such as literacy rates, life expectancy, and poverty rates. GDP does not take into account other aspects such as leisure time, environment quality, freedom, or social justice; alternative measures of economic well-being have been proposed. Essentialy, a country's economic development is related to its human development, which encompasses, among other things, health and education. These factors are, however, closely related to economic growth so that development and growth often go together.
