‘Seva Divas’ has been proposed by Central Government to celebrate the birthday of

The correct answer is B) Deen Dayal Upadhyay. The proposal was to observe his birth anniversary, 25 September, as Seva Divas, which the Centre linked to his Antyodaya philosophy of uplifting the last person in the queue.

• A) Atal Bihari Vajpayee: His birthday, 25 December, is marked as Good Governance Day, declared by the Centre in 2014. It is a different occasion, so this is a close but wrong pick.
• C) Shyama Prasad Mukherjee: He founded the Bharatiya Jana Sangh in 1951. His death anniversary, 23 June, is observed as Balidan Diwas, and his birth anniversary (6 July) is not linked to Seva Divas.
• D) Veer Savarkar: He is associated with the Hindu Mahasabha and the Andaman cellular jail. No central day of service was proposed in his name.

The core concept is the use of commemorative days to frame government schemes around a national figure's ideology. For Mains, link this to Antyodaya, the idea of welfare for the last person, which is central to GS-II and the ethics paper.

Trap: Aspirants see "25th day, December" and pick Vajpayee because Good Governance Day is famous. Check the exact occasion and the date it is tied to.
