Answer: Option (D) is correct.
Step-by-step explanation:
Given that,
In 2009:
Nominal GDP = 180 billion
GDP deflator = 105
In 2010:
Nominal GDP = 200 billion
GDP deflator = 125
GDP deflator measure the price level of the domestically produced final goods and services in an economy. Therefore, from the given information it was observed that GDP deflator increases from 105 in 2009 to 125 in 2010.
Hence, price level increases.
Nominal GDP is at a current market prices. Here, the percentage increase in the GDP deflator is greater than the percentage increase in nominal GDP. Hence, real output falls.
