Atal Nagar was announced as the new name for which planned capital city in the state of Chhattisgarh?

Introduction / Context:
Indian states sometimes rename cities to honour national leaders or reflect cultural identity. In the state of Chhattisgarh, a new planned capital city was developed to reduce pressure on the existing capital and provide modern infrastructure. This city was given a new name, Atal Nagar, in honour of former Prime Minister Atal Bihari Vajpayee. This question asks you to identify which planned capital city received this new name.

Given Data / Assumptions:

The context is the state of Chhattisgarh in central India.
A planned capital city was renamed Atal Nagar.
Options include Bilaspur, Naya Raipur, Raigarh and Bhilai, all cities in or associated with Chhattisgarh.

Concept / Approach:
Naya Raipur was developed as the new planned capital city of Chhattisgarh to share administrative functions with or replace the older capital of Raipur. Later, it was announced that this planned city would be renamed Atal Nagar in honour of Atal Bihari Vajpayee. Bilaspur is known as a major city in Chhattisgarh but not as the planned capital that received this new name. Raigarh and Bhilai are industrial and regional centres but also not the new capital. Recognising that Naya Raipur is the planned capital and that Atal Nagar is its new name leads directly to the correct answer.

Step-by-Step Solution:

Verification / Alternative check:
News reports and competitive exam materials discussing recent changes in city names have consistently mentioned that Naya Raipur in Chhattisgarh was renamed Atal Nagar. When reading sections on state capitals and their new names, Naya Raipur often appears alongside its new name in brackets. None of the other options Bilaspur, Raigarh or Bhilai are described as being renamed Atal Nagar, confirming that Naya Raipur is the correct answer.

Why Other Options Are Wrong:

Common Pitfalls:
Some students might confuse Raipur with Naya Raipur or think that the older capital itself was renamed, without recognising that Naya Raipur is the planned satellite and administrative city. Others may guess one of the more familiar industrial cities such as Bhilai due to its prominence in news related to steel production. To avoid these mistakes, clearly differentiate between the traditional capital, Raipur, and the planned capital, Naya Raipur, which has been renamed Atal Nagar.

Final Answer:
The correct answer is Naya Raipur, because Atal Nagar was announced as the new name for this planned capital city in Chhattisgarh.
