The GDP Deflator Differs from the CPI in Its Measurement

The GDP deflator differs from the CPI in its measurement of inflation in that:

A) it measures the price changes of all goods,not just those in a typical consumer's basket.
B) it uses the total quantities that are produced,not the ratio of what a typical consumer might consume.
C) it does not include imports,which may have a real effect on the typical consumer's cost of living.
D) All of these statements are true.
