B) a rightward movement along a horizontal short-run aggregate supply curve, a short-run increase in real GDP, an upward shift in the short-run aggregate supply curve, and an increase in the price level.
C) an leftward shift in a vertical short-run aggregate supply curve, a short-run decline in real GDP, an upward movement along the short-run aggregate supply curve, and an increase in the price level.
D) a rightward shift in a vertical short-run aggregate supply curve, a short-run increase in real GDP, an upward movement along the short-run aggregate supply curve, and an increase in the price level.
