Which set correctly matches primary, secondary, and tertiary economic activities?

• A. Agriculture; Forestry; Healthcare
• B. Fishing; Textiles; Software development
• C. Mining; Manufacturing; Healthcare
• D. Oil; Construction; Education

Answer: (C)

Economic activities are grouped by how much processing and value-adding they involve: primary covers extracting natural resources, secondary covers turning those resources into goods, and tertiary covers providing services to people. The sequence of mining, manufacturing, and healthcare fits this progression perfectly. Mining is extraction (primary), manufacturing takes those resources and makes products (secondary), and healthcare delivers services rather than goods (tertiary). The other options mix sectors that don’t clearly represent this straightforward three-stage chain within the typical classroom framework, or treat activities whose classification as tertiary can be debated. So this set shows the clearest primary–secondary–tertiary progression.
