Mazdoor Kisan Shakti Sangathan (MKSS), a Social Movement has been associated with which of the following in India?

The correct answer is B) RTI Act. The Mazdoor Kisan Shakti Sangathan, founded in Rajasthan in 1990 by Aruna Roy, Nikhil Dey and Shankar Singh, is the movement most closely tied to the Right to Information campaign. Its Jan Sunwai (public hearings) exposed muster-roll and bill fraud in village works by demanding that officials show the records. That demand for document access fed into the Rajasthan RTI Act, 2000, and then into the central RTI Act, 2005.

Why the others are wrong:

• A) RTE Act: The Right to Education Act, 2009 gave effect to Article 21A. It was shaped by education campaigns and Parliament, not by MKSS.
• C) MGNREGA: MKSS did push for the right to work and for social audits, and its work influenced the NREGA, 2005. But the movement is best known for the RTI, and that is the answer the question wants. Note this overlap, because it is where candidates slip.
• D) National Health Mission: NHM was launched in 2013 by merging the NRHM and NUHM. It has no link to MKSS.

Mains angle: the MKSS case shows how grassroots demands can become statutory rights, which is useful for answers on participatory governance and transparency.

Trap: Candidates pick MGNREGA because the movement is also linked to social audits. Identify the movement's most defining association, which here is the RTI.
