Secondary industry involves:

Secondary industry involves:

• A. Taking raw materials and turning them into products
• B. Providing services for customers
• C. Processing and transferring information
• D. Home-based services

Answer: (A)

Secondary industry covers manufacturing and processing activities that convert raw materials into finished goods. It sits between the primary sector (extracting or farming) and the tertiary sector (services). This is why the description "taking raw materials and turning them into products" is the best match: it directly describes the transformation at the heart of manufacturing. Examples include turning copper ore into wires, lumber into furniture, or assembling vehicles. The other descriptions point to services or information work rather than making physical products; providing services for customers, processing and transferring information, and home-based services belong to the service-focused sectors rather than the manufacturing-focused secondary sector.
