Which of the following Direct Benefit Scheme (DBS) has been recognized by the 'Guinness Book of World Record' as the world's largest Direct Benefit Scheme?

1. A

   MGNREGA

   MGNREGA is a demand-driven wage employment law with DBT of wages, but it is not the scheme Guinness listed as the world’s largest direct benefit transfer in this question.

2. B

   PAHAL

   PAHAL (Pratyaksh Hanstantrit Labh) — LPG subsidy transfer — was recognised by Guinness World Records as the world’s largest direct benefit transfer scheme. That is the official key.

3. C

   NSAP

   NSAP (National Social Assistance Programme) is pensions and related assistance, not the Guinness-tagged largest DBS here.

4. D

   None of the above

   A named scheme (PAHAL) exists, so ‘none’ is wrong.

Summary. Official key is (b) PAHAL. Guinness recorded the LPG DBT scheme as the world’s largest direct benefit transfer. MGNREGA and NSAP are different DBT families.
