Suppose the economy is at an equilibrium when C + 1 + G + X = $12 trillion. If the economy is currently at a real Gross Domestic Product (GDP) level of $13 trillion, then total planned real expenditures O A. are less than real Gross Domestic Product (GDP), and real Gross Domestic Product (GDP) will increase. O B. are equal to real Gross Domestic Product (GDP), and there will be no change in real Gross Domestic Product (GDP) O C. exceed real Gross Domestic Product (GDP), and real Gross Domestic Product (GDP) will increase. O D. are less than real Gross Domestic Product (GDP), and real Gross Domestic Product (GDP) will decline
