In the circular flow of income model, which of the following equations represents the correct relationship between the three different methods of measuring economic activity?
National Output=National Expenditure=National Income\text{National Output} = \text{National Expenditure} = \text{National Income}National Output=National Expenditure=National Income
National Income=Total Injections−Total Withdrawals\text{National Income} = \text{Total Injections} - \text{Total Withdrawals}National Income=Total Injections−Total Withdrawals
National Output=Total Consumption+Total Savings\text{National Output} = \text{Total Consumption} + \text{Total Savings}National Output=Total Consumption+Total Savings
National Expenditure=National Income+Total Injections\text{National Expenditure} = \text{National Income} + \text{Total Injections}National Expenditure=National Income+Total Injections
