a. changes in aggregate supply.
b. changes in aggregate demand.
c. changes in both aggregate demand and aggregate supply.
d. firms' greed.

c. changes in both aggregate demand and aggregate supply.

Explanation:

Aggregate demand which is also known as domestic final demand (DFD) refers to the demand of services and final goods in a specific market. On the other hand, aggregate supply refers to the supply of that service or final good to a specific market. Hence, it is the difference in the aggregate demand and aggregate supply of a product or good or service in a specific market. When the supply is lower than the demand, it automatically leads to inflation. There the option that changes in both aggregate demand and aggregate supply is correct.
