Economic Sectors and Infrastructure

India's economy is historically agrarian, and agriculture (including cultivation) remains the largest employer of labour, engaging around 40-50% of the workforce. The 'household sector' is not a standard economic classification for labour statistics. Manufacturing employs far fewer people compared to agriculture.

Option B has a typo ('TARDE' likely should be 'TRADE'), and fishing is not a primary occupation of this inland region.

Visakhapatnam (Vizag) is a major industrial hub hosting all these industries. It's home to Vizag Steel (a major steel plant), has multiple petroleum refineries and fertilizer complexes, features ship-building facilities (Hindustan Shipyard), and operates thermal power stations. This industrial diversity makes Vizag one of India's most important economic centers on the eastern coast.

Koraput in Odisha is home to a major aircraft manufacturing facility operated by HAL (Hindustan Aeronautics Limited). The Koraput division manufactures engines for aircraft like the MiG-21 and Tejas. It is not related to ship building, iron and steel, or locomotives.

Tourism is the largest industry in the Maldives, contributing nearly 30% to GDP and attracting over 1.5 million visitors annually to its luxury resorts and pristine islands. While fishing is the second-largest industry (notable for tuna exports), tourism dominates the economy. The Maldives has little mining activity, and exports consist mainly of fish, not manufacturing.

BEL (Bharat Electronics Limited) is an Indian electronics company specializing in defense electronics, telecommunications, and broadcasting equipment. It's a PSU under the Ministry of Defence.

BHEL (Bharat Heavy Electricals Limited) is India's largest engineering and manufacturing enterprise in the energy and infrastructure sector. It manufactures power plant equipment, turbines, and industrial machinery.

The public sector includes enterprises owned by the government, while the private sector consists of businesses owned by individuals or private companies. This classification is based on who owns and controls the economic activities, not on employment conditions or the type of raw materials used.

The textile industry is one of the largest sectors in India, employing millions of people and contributing significantly to GDP and exports. India has a long history of textile production, from ancient cotton weaving to modern garment manufacturing. While tea and rubber are important industries, textiles is the largest by employment and economic contribution.

The tertiary sector (services) contributes the largest share to India's national income, accounting for approximately 55-60% of GDP. This includes services like IT, banking, finance, insurance, real estate, telecommunications, tourism, and public services. India's economy has undergone structural transformation from agriculture-dominant to service-dominant since economic liberalization in 1991.
