Answer:
b. in the consumer price index, but not in the GDP deflator.
Step-by-step explanation:
CPI (Consumer price index) is a measure of the overall cost of the goods and services bought by a typical consumer.
GDP (gross domestic product) is the market value of all final goods and services produced within a country in a given period of time.
A GDP Deflator is a measure of the price level calculated as the ratio of nominal GDP to real GDP times 100. Basically, it determines the price changes of all goods and services produced within a country.
Since the price of imported coffee increases the CPI INCREASES because imported coffee is being bought by a typical consumer. But the GDP DEFLATOR WILL NOT CHANGE because imported coffee is not produced within the country.
