Answer:
c. the GDP deflator and the consumer price index.
Step-by-step explanation:
Two alternative measures of the overall level of prices are the GDP deflator and the consumer price index.
The GDP deflator can be defined as a measure of the changes in prices for all of the finished goods and services produced domestically in an economy in a particular period of time, usually a year. This simply means that, the gross domestic product deflator measures the inflation in an economy.
Consumer price index (CPI) can be defined as a measure of the aggregate or average changes in price level of a weighted market basket of finished goods and services that consumers purchased over a specific period of time. The CPI is also a measure of the inflation in an economy over a specific period of time.
