The correct answer is option 3, Manufactured product. The wholesale price index in India measures the average change in the prices of a basket of goods and services at the wholesale level. It is used to track inflation and understand the overall price trend in the economy.
The wholesale price index is calculated based on the weights assigned to different categories of goods and services. These weights reflect the relative importance of each category in the overall index.
In this case, the manufactured product category has the maximum weight in the wholesale price index. This means that changes in the prices of manufactured products have a larger impact on the overall index compared to other categories.
Primary articles, such as food items and raw materials, are important but have a lower weight in the index. Fuel and power, while significant, also have a lower weight compared to manufactured products.
Therefore, when tracking changes in the wholesale price index in India, it is the prices of manufactured products that have the greatest influence on the overall index.
