The correct answer is: Industrial development.
The initial Five-Year Plans in Tamil Nadu focused on industrial development. The state government invested heavily in infrastructure, such as roads, bridges, and power plants, to support the growth of industries. The government also provided incentives to businesses to invest in Tamil Nadu. As a result of these efforts, the state’s industrial sector grew rapidly during the 1950s and 1960s.
The other options are incorrect. Infrastructure building was a focus of the Five-Year Plans, but it was not the key focus. Agricultural modernization was also a focus, but it was not as important as industrial development. Social welfare schemes were not a focus of the Five-Year Plans.
Here is a brief explanation of each option:
- Industrial development is the process of increasing the amount of industrial activity in a country or region. This can be done by building new factories, investing in existing factories, and providing incentives to businesses to invest in industry.
- Infrastructure building is the process of building and maintaining the physical structures and systems that are necessary for a country or region to function. This includes roads, bridges, airports, power plants, and water systems.
- Agricultural modernization is the process of improving the efficiency and productivity of agriculture. This can be done by using new technologies, such as tractors and irrigation systems, and by adopting new farming practices.
- Social welfare schemes are government programs that provide assistance to people who are in need. This can include programs that provide food, housing, healthcare, and education.
