Option D

The customer price index (CPI) is described as the calculated average price of the bundle of goods and services like medical costs, transportation, food, etc. and it is calculated or compared with the CPI of the index reference period normally referred to as the base year. It is calculated by averaging the prices of the basket goods and it is used to determine the cost of living.

Comparing CPI from different periods requires evaluating the fixed basked of goods during the base period and examining the consumption patterns over time. It can also be represented as a ratio of base period to the current period or period of interest.
