Which municipal corporation won the first prize at the Swachhata Excellence Awards 2019 for its solid waste management and cleanliness initiatives?

Introduction / Context:
The Swachhata Excellence Awards are part of wider efforts under the Swachh Bharat Mission to recognise urban local bodies that perform well in cleanliness and solid waste management. Municipal corporations that innovate and sustain good practices in sanitation, segregation and waste processing are honoured. This question asks which municipal corporation received the first prize at the Swachhata Excellence Awards 2019.

Given Data / Assumptions:
- The focus is on the Swachhata Excellence Awards for the year 2019.
- The question is concerned with the municipal corporation that received the first prize.
- Four municipal corporations from different cities are listed as options.

Concept / Approach:
Raigarh Municipal Corporation in Chhattisgarh gained recognition for its efficient solid waste management system, including door to door collection, segregation at source and effective processing. Its efforts were acknowledged at the national level, and it received the first prize at the Swachhata Excellence Awards 2019. Remembering the association of Raigarh with Swachhata awards can help in answering related questions.

Step-by-Step Solution:
Step 1: Identify that the question refers specifically to the Swachhata Excellence Awards 2019, not other cleanliness rankings like Swachh Survekshan. Step 2: Recall that Raigarh Municipal Corporation was widely reported as the first prize winner in this category for its waste management system. Step 3: Arrah, Jagdalpur and Ahmedabad are important cities, but their municipal corporations were not cited as first prize winners in this particular award list for 2019. Step 4: Therefore, among the given options, Raigarh Municipal Corporation is the correct choice.

Verification / Alternative check:
You can verify by consulting summaries of the Swachhata Excellence Awards for 2019 in current affairs compilations, which highlight Raigarh Municipal Corporation as a top performer. The mention of innovative practices and community participation is often linked with this municipal body.

Why Other Options Are Wrong:
- Arrah Municipal Corporation: Not recorded as the first prize winner in the Swachhata Excellence Awards 2019.
- Jagdalpur Municipal Corporation: May have its own initiatives, but not the first prize recipient in this award year.
- Ahmedabad Municipal Corporation: A large and important municipal body, but not the one recognised with this specific first prize in 2019.

Common Pitfalls:
Students sometimes confuse different cleanliness related rankings and awards, such as Swachh Survekshan city rankings and Swachhata Excellence Awards. Another pitfall is to assume that a very large metro city must have won every major award, whereas sometimes smaller or medium sized cities are recognised for innovative work. To avoid errors, link specific awards and years to particular cities like Raigarh in 2019.

Final Answer:
The first prize at the Swachhata Excellence Awards 2019 went to Raigarh Municipal Corporation.
