'Rashtriya Garima Abhiyaan' is a national campaign to

1. A

   Rehabilitate the homeless and destitute persons and provide them with suitable sources of livelihood

   Homeless rehabilitation. Shelter and livelihood for destitute persons is not what Rashtriya Garima Abhiyaan names. This letter is not the key.

2. B

   Release the sex workers from their practice and provide them with alternative sources of livelihood

   Sex-worker release and livelihood. That is a different social-welfare frame, not this campaign’s title. This letter is not the key.

3. C

   Eradicate the practice of manual scavenging and rehabilitate the manual scavengers

   Eradicate manual scavenging and rehabilitate scavengers. Rashtriya Garima Abhiyaan is the national campaign associated with ending manual scavenging and restoring dignity, linked to the 2013 prohibition law’s spirit. That stored letter is the official key.

4. D

   Release the bonded labourers from their bondage and rehabilitate them

   Bonded-labour release. Bonded labour has its own 1976 Act and rehabilitation schemes; it is not this campaign’s label. This letter is not the key.

Summary. Official key is (c) eradicate manual scavenging and rehabilitate manual scavengers. Rashtriya Garima Abhiyaan is that dignity campaign, not a generic homeless, sex-work or bonded-labour programme. Honour the stored letter (c).
