When government spending increases, aggregate demand shifts to the right from AD2 to a new AD curve to reflect the increase in government spending. The economy moves from point A to a new short-run equilibrium point, where the intersection of the new AD curve and the SRAS1 curve determines the new equilibrium price level and real GDP. However, in the long-run, wages and prices adjust to the increase in demand, causing the SRAS curves to shift to the left. The eventual long-run equilibrium will be where the LRAS curve intersects the new AD curve, which, based on the graph, is at point C. Therefore, the best choice is C.
