What measure does the Federal Reserve prefer to use rather than the CPI, and why does it prefer that measure? A. Personal Consumption Expenditure (PCE) Index, because it is broader and tracks the prices of more goods and services than does the CPI. B. Produce Price Index (PPI), because it focuses on the price sellers receive for providing their goods or services. C. Personal Consumption Expenditure (PCE) Index, because it eliminates volatile prices such as rent and gasoline. D. GDP deflator, because it includes the prices of all goods and services sold within the country
