Answer:
C) The long-run aggregate supply curve will shift to the right
Explanation:
The long-run aggregate supply curve is vertical because it is thought that demand does not affect supply in the long run.
Supply in the long run is therefore only affected by the factors of production: land, labor, capital, and entrepreneurship (although whether entrepreneurship is a factor of production is a subject of debate among economists).
A curve shifts when an exogenous variable (a variable that is not graphically represented on the coordinated system of the model) changes. In the AS-AD model, labor is an exogenous variable, and a change in labor will therefore shift the supply curve.
If immigrants are forced to leave the US, the labor force will shrink. As output depends on labor, output will be less than before, and this in turn will reduce the aggregate supply in the economy, and make the long-run aggregate supply curve shift to the left.
