Explanation
The question tests the student's understanding of the classification of economic activities, specifically differentiating between the organised and unorganised sectors, and public and private sectors. For options (i), (ii), and (iii), the primary distinction is based on the nature of employment and job security (Organised vs Unorganised). The organised sector provides job security, fixed working hours, and registered employment, while the unorganised sector lacks these benefits. For option (iv), the distinction is based on ownership (Public vs Private). Public sector enterprises are owned by the government, while private sector enterprises are owned by individuals or private companies.
