B. Construction
Read Explanation:
In economics, the "Secondary Sector" refers to industries that produce a finished, usable product or are involved in construction. It takes the raw materials provided by the primary sector and transforms them into goods through manufacturing and processing.
Construction is grouped with manufacturing because it involves "building" or "assembling" something new from raw inputs (like wood, steel, and cement). Whether it's a skyscraper, a bridge, or a house, the process transforms raw materials into a permanent structure.
Mining (Primary): You are taking minerals directly out of the earth.
Banking & Trade (Tertiary): These don't "make" a physical object; they provide the financial systems and the distribution networks that keep the other sectors moving.
