Let's examine each statement regarding Gopal Krishna Gokhale: 1. He started "Servants of Indian Society" in 1905: This is correct. Gokhale founded the Servants of India Society in Pune in 1905 with the aim of training Indians for selfless service to the nation. 2. He went in to South Africa and helped Gandhi in his movement against Colour bar: This is correct. Gokhale visited South Africa in 1912 at Gandhi's invitation to support the Indian community's struggle against racial discrimination. His visit helped garner support for Gandhi's cause in India and internationally. 3. Gandhi accepted Gokhale as 'Political guru': This is correct. Mahatma Gandhi considered Gokhale as his political mentor and spiritual guide in the Indian freedom struggle. 4. Gandhi described Gokhale as diamond of India, the Jewel of Maharastra and Prince of Workers: While Gandhi held Gokhale in extremely high regard and used effusive terms to describe him, the exact combination "diamond of India, the Jewel of Maharastra and Prince of Workers" is not a standard or precise quote widely attributed to Gandhi. Gandhi did refer to Gokhale as 'Gokhale the Good' and 'Jewel of India' and praised his dedication to service ('Prince of Workers' might be a misattribution or less common title used by Gandhi compared to others). Given that statements 1, 2, and 3 are historical facts, statement 4 is the most likely to be considered incorrect due to the specific phrasing or combination of titles used.
