सन 1988 पासून ज्योतिबा फुले हे 'महात्मा' म्हणून का ओळखले जावू लागले ?

The correct answer is Option C (He worked day and night for the lower caste people).

Key Points:
• Conferment of 'Mahatma' Title on Jyotirao Phule:
• On 11th May 1888 (printed as 1988 in exam paper typo), in a massive public felicitation at Mandvi Koliwada Hall in Mumbai, the title 'Mahatma' (Great Soul) was conferred on Jyotirao Phule by social reformer Rao Bahadur Vithalrao Krishnaji Vandekar on behalf of the public.
• This honour recognized his tireless, pioneering, day-and-night crusade for the liberation, human rights, education, and social emancipation of the lower-caste Shudras, Ati-Shudras, and downtrodden masses.
• Phule established the first indigenous schools for girls (1848) and Dalits (1851), opened his water reservoir to untouchables (1868), and founded the Satyashodhak Samaj (1873) to dismantle caste hegemony.
• Key Takeaway: Jyotiba Phule was conferred the title 'Mahatma' in 1888 for his tireless crusade for the upliftment of lower-caste communities.
