AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Basis: Nature of activity — the economy is classified into primary, secondary, and tertiary sectors. Example: Agriculture belongs to the primary sector.
This 1-mark question needs just one basis + one valid example. The three main bases from the chapter are: (1) nature of activity → primary/secondary/tertiary, (2) employment conditions → organised/unorganised, (3) ownership → public/private. Any one pair is acceptable. Keep it to a single line.
