Explanation:

Option 4th is odd one out.

Index of Industrial Production (IIP)

• The Index of Industrial Production (IIP) is an index that shows the growth rates in different industry groups of the economy in a fixed period of time.

• It is compiled and published monthly by the Central Statistical Organization (CSO), Ministry of Statistics and Programme Implementation.

• IIP is a composite indicator that measures the growth rate of industry groups classified under:

• Broad sectors, namely, Mining, Manufacturing, and Electricity.

• Use-based sectors, namely Basic Goods, Capital Goods, and Intermediate Goods.

• Sectors included: Mining, Manufacturing, and Electricity

• Excluded sectors: Services like retail, banking, education, healthcare

• Reason for exclusion: Difficulty in obtaining reliable data for service sector activities 

• Note: Gas and Water Supply: This sector is not part of the IIP's measured sectors. IIP mainly focuses on industrial production rather than utilities.

Hence option 4th is correct.
