Why Correct: As of 2017, the service sector contributed over 50% of India's GDP, making it the largest sector in the economy. This reflects the post-liberalization shift from agriculture to services.
Distractor Analysis: 33% of GDP was the approximate share of industry. 40% and 42% are below the actual service sector share. Only 50%+ matches the documented contribution.
Takeaway: India's service sector accounts for more than half of GDP, driven by IT, finance, and trade.

Why Correct: The tertiary sector involves services rather than goods production. Infrastructure services such as transportation, banking, and communication are classic examples of tertiary activities.
Distractor Analysis: Cottage industries belong to the secondary sector (manufacturing). Mining activities are part of the primary sector (extraction of raw materials). Construction activities are also part of the secondary sector (building and infrastructure creation).
Takeaway: The three-sector model classifies economic activities into primary (agriculture, mining), secondary (manufacturing, construction), and tertiary (services). Infrastructure services like roads, telecom, and finance are key tertiary sector activities.

Why Correct: Irrigation in India is predominantly state-owned, with major projects managed by public sector enterprises like state irrigation departments.
Distractor Analysis: Agriculture is primarily private sector, with land owned by individuals. Forestry is managed by state forest departments but is not primarily a service sector. Plantations are largely private enterprises (tea, coffee, rubber).
Takeaway: Public enterprises dominate sectors with high capital requirements or strategic importance, such as irrigation.

Why Correct: The services sector contributes about 60% of India’s GDP, the highest among all sectors.
Distractor Analysis: Agriculture contributes around 15-18% of GDP. Industry contributes around 25-30%. Foreign trade is not a sector but a component of the external sector.
Takeaway: Services have been the dominant contributor to India’s GDP since the 1990s, while agriculture employs the most workers.
