Answer: Option (B) is correct.
Explanation:
The nominal GDP is equal to the real GDP in the base year, that's why GDP deflator in the base year is equal to 100.
GDP deflator is calculated as the nominal GDP divided by the real GDP multiply by 100. It is shown as:
GDP deflator = [tex]\frac{Nominal\ GDP}{Real\ GDP} \times 100[/tex]
GDP deflator would be used as the conversion factor that transformed the real GDP into nominal GDP.
