The correct option is 1 and 3 only.
Explanation
Economic activities are classified into sectors based on ownership of assets and responsibility for the delivery of services. The primary distinction lies between the public sector and the private sector.
Statement-wise Analysis:
- Statement 1 is Correct: The public sector comprises organizations and enterprises where the government owns the majority of assets and assumes the responsibility for delivering services. Examples include railways and post offices.
- Statement 2 is Incorrect: The public sector does not provide all services in an economy. In a mixed economy, the private sector plays a significant role in providing goods and services. Private individuals and companies own assets and deliver services guided by the profit motive.
- Statement 3 is Correct: While the primary objective of the public sector is social welfare rather than profit maximization, public sector enterprises do generate revenue. They charge for the goods and services they provide (e.g., train tickets, electricity charges) to sustain operations and cover costs.
Key Takeaway:
The public sector is defined by government ownership of assets and service delivery, whereas the private sector is driven by private ownership and profit. However, public sector entities also generate revenue to maintain financial sustainability.
