Identify the component of social environment from the following:

Option 1 -> Savings and Investment is an economic component that reflects financial behavior and capital formation in an economy.

Option 2 -> Money Supply is an economic/monetary component that represents the total amount of money circulating in an economy.

Option 3 -> Public Debt is an economic/fiscal component that indicates the total borrowing obligations of the government.

Option 4 -> Life Expectancy is a social indicator that reflects the health, living standards, and quality of life of a population.

Hence, Option 4: Life Expectancy -> Life expectancy is a demographic and social indicator that directly relates to the social environment as it measures the average lifespan of people in a society, reflecting healthcare quality, nutrition, sanitation, education, and overall living conditions. The other three options are all economic components, not social environment factors -> correct
