The correct answer is C, Total Budget Deficit; $900.
Budget Deficit comprises of two deficits. One is Structural Deficit and the other is Cyclical Deficit. The cyclical deficit happens when there is an imbalance in the business cycle. Tax receipts are going down and spending are going up, then cyclical deficit increases. Similarly, structural deficit occurs when there is an imbalance in the government receipts and expenditures. So collectively they are called the Total Budget Deficit.
