Correct answer: (b) RTI Act
Explanation
- A
RTE Act
The Right to Education Act, 2009, grew from a different campaign (education as a fundamental right). MKSS is not primarily identified with RTE in this question.
- B
RTI Act
Mazdoor Kisan Shakti Sangathan, founded in Rajasthan (Aruna Roy, Nikhil Dey and others), led the grassroots right-to-information movement (public hearings, jan sunwai) that fed the RTI Act, 2005. That is the official key. (Hindi options in the source file are OCR-scrambled; English options A RTE, B RTI, C MGNREGA, D NHM are the intended list.)
- C
MGNREGA
MKSS also fought for rural wages and transparency in works, which later connected to NREGA, but the landmark association in this item is RTI, not MGNREGA as the keyed answer.
- D
National Health Mission (NHM)
The National Health Mission is a health-systems programme, not an MKSS identity.
Summary. Official key is (b) RTI Act. MKSS of Rajasthan pioneered jan sunwais that built the national right-to-information campaign. RTE, NREGA and NHM are other laws/missions.
