Which Indian state was declared the best state for active participation in the Swasth Bharat Yatra health awareness campaign?

Introduction / Context:
The Swasth Bharat Yatra was a large scale pan India campaign organised to promote safe food, healthy eating, and an active lifestyle. This question tests general awareness about important national level health initiatives and the recognition given to different Indian states for their active participation in such campaigns. Knowing which state was declared the best for participation in the Swasth Bharat Yatra helps students connect current affairs with public health policy and government programmes.

Given Data / Assumptions:
- The Swasth Bharat Yatra was a national campaign on food safety and healthy living.
- Several Indian states participated in this campaign through events, citizen engagement and outreach activities.
- An award for the best state for active participation was given based on performance in the campaign.
- The options list four Indian states: Karnataka, Telangana, Tamil Nadu and Uttar Pradesh.

Concept / Approach:
To answer this question, we need to recall factual information from current affairs related to health and nutrition campaigns in India. The Food Safety and Standards Authority of India (FSSAI) coordinated the Swasth Bharat Yatra, and at the end of the campaign certain states were recognised for their performance. The correct state is the one officially declared as the best state for active participation, based on metrics such as number of events, citizen mobilisation and outreach quality.

Step-by-Step Solution:
Step 1: Recall that Swasth Bharat Yatra was organised by FSSAI to promote safe and healthy food habits through a nationwide cyclothon and related events. Step 2: Remember that several states were evaluated for their performance in organising activities, mobilising citizens and spreading awareness during the campaign. Step 3: Among the states listed, Tamil Nadu received national recognition as the best performing state for active participation in the Swasth Bharat Yatra. Step 4: Compare this recollection with the options provided and identify Tamil Nadu as the correct choice.

Verification / Alternative check:
A quick way to verify is to recall news reports and government press releases summarising the outcome of the Swasth Bharat Yatra. These mentioned Tamil Nadu as the state that excelled in organising events, engaging citizens, and integrating the campaign with local initiatives on nutrition and health. No similar recognition was widely reported for Karnataka, Telangana or Uttar Pradesh in the context of being the best state for active participation in this specific campaign.

Why Other Options Are Wrong:
- Karnataka: It participated in the campaign but was not declared the best state for active participation in Swasth Bharat Yatra.
- Telangana: Also involved in health campaigns, but it did not receive the specific recognition as top state for this yatra.
- Uttar Pradesh: A large state with many programmes, but it was not named the best performing state for Swasth Bharat Yatra participation.

Common Pitfalls:
Students may confuse awards related to other health programmes or nutrition missions with Swasth Bharat Yatra and therefore pick a wrong state. Another error is to assume that the most populous state or a frequently mentioned state in the news must automatically be the winner. It is important to connect the question clearly to the specific campaign name and recall the exact state recognised in that context.

Final Answer:
The Indian state declared the best for active participation in the Swasth Bharat Yatra health awareness campaign is Tamil Nadu.
