विनायक सावरकर, त्र्यंबकराव म्हसकर व रावजी कृष्णा यांनी नाशिक येथे प्रथम कोणती संस्था स्थापन केली ?

The correct answer is Option B (Rashtrabhakt Samuh).

Key Points:
• Evolution of Savarkar's Secret Revolutionary Societies:
• In 1899 at Nashik, Vinayak Damodar Savarkar along with his close nationalist companions Trimbakrao Mhaskar, Ravji Krishna, and others initially founded a secret youth group called 'Rashtrabhakt Samuh' (राष्ट्रभक्त समूह).
• On 1 January 1900, this circle was formalized into the open and socio-cultural organization 'Mitra Mela' to celebrate Ganesh Utsav and Shivaji Utsav with patriotic songs and physical culture.
• In May 1904, in a meeting attended by around 200 members at Nashik, Mitra Mela was transformed into the secret revolutionary society 'Abhinav Bharat' (modelled on Giuseppe Mazzini's Young Italy).
• Officially, MPSC validated 'Rashtrabhakt Samuh' as the earliest organizational root established by this trio in Nashik.
• Key Takeaway: Vinayak Savarkar, Trimbakrao Mhaskar, and Ravji Krishna first founded 'Rashtrabhakt Samuh' (1899) in Nashik before Mitra Mela.
