Who among the following may be called the first prose writer of Rajasthani…

Rajasthani literary tradition includes long-established forms such as dohas and geet (courtly and devotional verse) alongside vachanikas and khyats (historical and narrative prose chronicles composed by court chroniclers and Charans). Modern literary prose genres — the novel, the short story, and the stage play as distinct forms — however, developed later, and literary historians credit specific early-1900s works and writers with founding each of these modern genres in Rajasthani.

Shiv Chandra Bhartiya, referred to as the "Bharatendu Harishchandra of Rajasthan," is credited with this founding role: his play "Kesar-Vilas" (1900) is regarded as Rajasthani's first modern play, his novel "Kanak-Sundari" (1903) as its first modern novel, and his story "Vishrant Pravas" (1904) as its first modern short story — together the basis on which he is recognised as the first prose writer of modern Rajasthani literature, matching the official RSSB Patwar 2025 (Shift II) answer key.

• Lakshmi Kumari Chundawat is remembered for compiling Rajasthani folk epics and doha collections and for her advocacy of the language's constitutional recognition — a research and preservation contribution rather than the founding prose works described above.

• Yadvendra Sharma "Chandra" is a later Rajasthani-Hindi novelist, known for historical fiction such as "Gora Badal" — a work that follows, rather than founds, the Rajasthani prose tradition.

• Rameshwar Dayal is associated with Rajasthani ghazal composition and translation work, a poetic and translated body of work rather than the founding prose works described above.

Hence, among the options, Shiv Chandra Bhartiya is the writer credited as the first prose writer of modern Rajasthani literature.
