जात पात तोडक मंडळाच्या लाहोर येथील वार्षिक संमेलनासाठी डॉ. बाबासाहेब आंबेडकरानी दिलेले भाषण म्हणजे ___ हा ग्रंथ होय.

The correct answer is Option C (Annihilation of Caste).

Key Points:
• Annihilation of Caste (1936):
• In 1936, the 'Jat-Pat Todak Mandal' (a reformist Hindu organization based in Lahore) invited Dr. Babasaheb Ambedkar to deliver the Presidential Address at their annual conference.
• Dr. Ambedkar prepared an uncompromising, profoundly analytical critique of the Hindu caste system and religious scriptures.
• Cancellation & Publication:
• When the organizers read the text in advance, they requested him to tone down and remove his fundamental criticisms of the Shastras and Vedas. Dr. Ambedkar refused to change even a comma.
• Consequently, the committee cancelled the conference. Dr. Ambedkar then self-published the undelivered address at his own expense in May 1936 under the title 'Annihilation of Caste' (जाती प्रथा निर्मूलन), which became one of the greatest socio-political treatises in world literature.
• Other Works:
• 'Castes in India: Their Mechanism, Genesis and Development' (1916 Paper).
• 'Who Were the Shudras?' (1946).
• 'Riddles in Hinduism' (Published posthumously).
• Key Takeaway: Dr. Ambedkar's undelivered 1936 Lahore presidential address for Jat-Pat Todak Mandal was published as 'Annihilation of Caste'.
