Name the founder of the prominent Rajasthani journal “Maruvani”.

Concept: Rajasthan's modern literary journalism grew through dedicated language-promotion societies (sabhas) — literary figures formed such a sabha, which then launched a periodical to standardise the regional language, publish original writing, and build readership for it. Identifying a journal's founder means tracing which society or individual actually established and launched that specific publication.

Application: The monthly journal Maruvani, the first Rajasthani-language periodical devoted to that language's study and literature, was launched by the Rajasthani Bhasha Prachar Sabha (Rajasthani Language Promotion Society). This Sabha was set up through the joint effort of the Dingal poet Chandra Singh Birkali — popularly known as Kavi Chandra Singh — together with scholar-editor Rawat Saraswat; under it, Maruvani ran for roughly two decades as a major platform for Rajasthani writers. RSSB's official answer key for this Patwar 2025 (Shift 2, Q126) paper credits Chandra Singh Birkali, i.e. the option “Kavi Chandra Singh”, as the founder.

Cross-check: Independent Rajasthani-literature reference material on Chandra Singh Birkali’s life corroborates this, documenting that he worked collaboratively with Rawat Saraswat to establish the Rajasthani Bhasha Prachar Sabha and launch Maruvani — matching the official key.

Contrast with the other names offered:

• Kishore Kalpna Kant is documented as a Rajasthani poet (works such as ‘Kookh Padiyai Ri Peed’ catalogued in the Kavita Kosh poetry repository), not as a founder of the Rajasthani Bhasha Prachar Sabha or Maruvani.

• Satya Prakash Joshi is a Rajasthani litterateur honoured with the Sahitya Akademi Award (1977) for the work ‘Bol Bharmali’, with no documented role in launching Maruvani.

• Dr. Manohar Sharma is a Rajasthani poet-editor known for works such as ‘Rohide Ra Phool’, and is not credited in available reference material as Maruvani’s founder.
