The Department for Promotion of Industry and Internal Trade (DPIIT) has revised the base year index of Eight Core Industries having a combined weight of about 40.27 percent in the Index of Industrial Production. Which one of the following is not one of the Eight Core Industries?

The Index of Eight Core Industries (ICI) measures the collective and individual performance of production in eight specific sectors: Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement, and Electricity [7]. These industries represent approximately 40.27% of the weight of items included in the Index of Industrial Production (IIP) [4]. The Department for Promotion of Industry and Internal Trade (DPIIT), through the Office of the Economic Adviser, compiles and releases this index with a base year of 2011-12 [6]. Among the options provided, Coal, Refinery Products, and Cement are explicitly listed as core industries [2]. Rubber products are not part of the eight core industries; instead, they are categorized under broader manufacturing groups within the general IIP but do not hold the 'core' designation [5]. Refinery products carry the highest weight (28.04%) within the ICI [4].
