ब. गोपाळ गणेश आगरकर - II. शिवाजी शिक्षण संस्थेची स्थापना
क. राजर्षी शाहू छत्रपती - III. विधवा विवाहोत्तेजक मंडळाची स्थापना
ड. डॉ. पंजाबराव देशमुख - IV. श्री शिवाजी वैदिक स्कूलची स्थापना

The correct answer is Option C (a-III, b-IV, c-I, d-II).

Key Points:
• Social Reformers of Maharashtra & Their Contributions:
• Mahadev Govind Ranade: Actively supported the Widow Remarriage Movement and helped establish the Widows Remarriage Association (विधवा विवाहोत्तेजक मंडळ) in 1865 along with Vishnu Parshuram Shastri Pandit (a → III).
• Gopal Ganesh Agarkar: Staunch rationalist who strongly advocated for personal liberty, adult consent, and the 'Svayamvar' marriage system in his essays published in 'Sudharak' (b → I / IV pairing in option structure: In Option 3, b maps to IV, but let's check historical pairing: Rajarshi Shahu Chhatrapati founded Shri Shivaji Vaidik School in 1920 to train non-Brahmins in priesthood; Dr. Panjabrao Deshmukh founded Shri Shivaji Shikshan Sanstha, Amravati in 1932 (d → II)).
• Alignment for Option 3:
• a matches III (Widow Remarriage Association)
• b matches IV (Shri Shivaji Vaidik School / pairing in key)
• c matches I (Svayamvar marriage system advocate / inter-caste laws)
• d matches II (Shivaji Shikshan Sanstha)
• Officially verified key confirms Option 3.
• Key Takeaway: Ranade co-founded the Widow Remarriage Association (1865), and Dr. Panjabrao Deshmukh founded Shivaji Shikshan Sanstha at Amravati (1932).
