The correct answer is (a) 2002.
The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. The CPI is a statistical indicator of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. The CPI is constructed from the prices of a sample of consumer goods and services that are purchased by urban consumers. The CPI is used to track inflation and to adjust wages, salaries, and pensions.
The base year for the CPI is the year in which the prices of the goods and services in the market basket are set to equal 100. The CPI for a given year is calculated by dividing the prices of the goods and services in the market basket in that year by the prices of the goods and services in the market basket in the base year and multiplying by 100.
The base year for the CPI for industrial workers was changed from 1982 to 2002. This change was made to reflect the changes in the prices of goods and services that are purchased by industrial workers. The CPI for industrial workers is used to track inflation and to adjust wages, salaries, and pensions for industrial workers.
The other options are incorrect because they are not the base year for the CPI for industrial workers.
