इ. स. १९१७ मध्ये खामगांव येथे भरलेल्या मराठा शिक्षण परिषडेच्या अकराव्या अधिवेशनात निदान दहा वर्षे तरी जातवार प्रतिनिधी निवडून देण्याचा हक्क असावा अशी जाहीर मागणी _____ यांनी केली.

The correct answer is Option D (Rajarshi Shahu Maharaj).

Key Points:
• Maratha Shikshan Parishad & Rajarshi Shahu Maharaj:
• The 11th session of the Maratha Shikshan Parishad (मराठा शिक्षण परिषद) was held at Khamgaon (Buldhana district) in December 1917 under the presidency of Rajarshi Chhatrapati Shahu Maharaj of Kolhapur.
• In his historic presidential address, Shahu Maharaj strongly advocated for communal representation in legislative councils for backward and non-Brahmin communities.
• He publicly declared: "For at least ten years, caste-based representation (जातवार प्रतिनिधित्व) must be granted by law to backward classes so that they learn to protect their own political rights and governance."
• This demand played a critical role in shaping the Montagu-Chelmsford Reforms (1919) and the subsequent reservation of seats for Marathas and allied castes in the Bombay Legislative Council.
• Therefore, Rajarshi Shahu Maharaj made this historic declaration (Option 4).
• Key Takeaway: At the 1917 Khamgaon Maratha Shikshan Parishad, Rajarshi Shahu Maharaj demanded caste-based representation for at least 10 years.
