Who among the following actresses is the brand ambassador of ‘Nirmal Bharat Abhiyan’?

Correct answer: B (Vidya Balan). Vidya Balan was named the brand ambassador of Nirmal Bharat Abhiyan, the Ministry of Drinking Water and Sanitation's sanitation campaign focused on rural toilets, household hygiene and open defecation-free villages. The question tests whether you can link celebrity endorsements to specific government campaigns, which the UPPSC has repeatedly asked.

• A (Madhuri Dixit): Not linked to Nirmal Bharat Abhiyan. Aspirants often confuse her with sanitation-related publicity from other campaigns.
• C (Priyanka Chopra): Associated with other social and UN-linked causes, not this campaign.
• D (Parineeti Chopra): Not the NBA ambassador.

Note that Nirmal Bharat Abhiyan was subsumed into the Swachh Bharat Mission (Gramin) after 2014, so the ambassador link is best remembered as a historical fact of the earlier campaign. In Mains, the broader angle is how awareness-led campaigns complement infrastructure schemes in sanitation governance.

Trap: Mixing up the Swachh Bharat Abhiyan ambassadors with those of Nirmal Bharat Abhiyan, since the two campaigns overlap in name and theme.
