The correct option is C Campaigning
The passing of the RTI Act was not an easy task. It took decades of activism in order to get the bill passed. The Mazdoor Kisan Shakti Sangathan or the MKSS and the National Campaign on People's Right to Information (NCPRI) played a noteworthy role in getting the RTI act passed. For decades, the MKSS used various modes of struggle, advocacy and campaigning to initiate the movement for the RTI.
