With reference to the sectors of the Indian economy, consider the following pairs : Economic activity : Sector 1. Storage of agricultural produce : Secondary 2. Dairy farm : Primary 3. Mineral exploration : Tertiary 4. Weaving cloth : Secondary How many of the pairs given above are correctly matched ?

The correct answer is (b) because only pairs 2 (Dairy farm - Primary) and 4 (Weaving cloth - Secondary) are correctly matched, testing the core concept of classifying economic activities based on their production process. Dairy farming involves the direct exploitation of natural resources (Primary), and weaving involves manufacturing goods from raw materials (Secondary), whereas storage is a service (Tertiary) and mineral exploration is an extractive activity (Primary). Option (c) is the most tempting wrong choice for candidates who mistakenly classify mineral exploration as a professional service or storage as an industrial activity.
