The correct answer is:

long-run equilibrium occurs at the intersection of the aggregate demand curve, the short-run aggregate supply curve, and the long-run aggregate supply curve.

In the extended aggregate demand-aggregate supply model, long-run equilibrium occurs when all three curves intersect, indicating that the economy is at full employment with stable prices.
