To encourage balanced regional development, Tamil Nadu offers incentives for industries setting up in:

Tier 1 Cities
Backward Districts
Coastal Zones
Metropolitan Areas

The correct answer is: Backward Districts.

Tamil Nadu offers incentives for industries setting up in backward districts to encourage balanced regional development. These incentives include tax breaks, land subsidies, and access to infrastructure. The goal of these incentives is to attract investment to these districts and help them to develop economically.

Tier 1 cities are already well-developed and have a strong economy. As a result, they do not need as much government support as backward districts. Coastal zones are important for the state’s economy, but they also face environmental challenges. Metropolitan areas are home to a large number of people and businesses. As a result, they have their own unique set of challenges.

By offering incentives for industries to set up in backward districts, the Tamil Nadu government is hoping to create jobs and boost economic growth in these areas. This will help to reduce poverty and inequality in the state. It will also help to make the state more competitive in the global economy.
