Which of the following is a primary activity of the secondary sector in the economy?

The secondary sector of the economy focuses on turning raw materials into finished goods. This means that businesses in this sector take resources from the primary sector, like farming or mining, and transform them into products we can use or sell. For example, a factory that takes steel and makes cars is part of the secondary sector. This activity is crucial because it adds value to raw materials, creating jobs and driving economic growth. So, when we think of the secondary sector, we are looking at activities like manufacturing, construction, and processing.
