Answer:
The answer is: D) slopes upward to the right due to short-run fixed costs of production.
Step-by-step explanation:
In the short run, companies have fixed factors of production: prices, wages, and capital. In the short run, aggregate supply curve shows the correlation between the price level and output (normal supply curve). Only in case of a production increase due to technological improvements or other factors (decreasing input prices, etc), may the aggregate supply curve shift outward.
