Industries are broadly classified into

Industries are broadly classified into three sectors: primary, secondary, and tertiary. This is the standard three-sector model used in economics and geography to categorise all economic activities.

• Primary industries extract raw materials directly from nature. Examples include farming, fishing, mining, forestry, and quarrying.
• Secondary industries process and manufacture raw materials into finished or semi-finished goods. Examples include food processing, textile manufacturing, steel production, and construction.
• Tertiary industries provide services rather than tangible goods. Examples include banking, education, healthcare, transport, and retail trade.

The option listing "primary, secondary, and manufacturing" is incorrect because manufacturing is a subset of the secondary sector, not a separate broad classification alongside it. Using manufacturing as a third category creates an overlap with secondary.

The other two options (fishing, mining, and food processing; or mining, furniture making, and cocoa processing) list specific industries rather than broad classifications. These are examples of industries within the primary and secondary sectors, not the categories themselves.
