Respuesta :

Answer:

The correct answer is option C.

Explanation:

In the long run, the aggregate supply curve is a vertical line. It does not change with the change in price. This is because when the price of a product increases in the long run, the input prices increase as well. So the supply will remain constant.  

This is why the level of real GDP will be unaffected by the price level. The long-run aggregate supply will increase because of technological change or an increase in resources.
