दक्षिणी संस्थान हितवर्धक सभेच्या शाखा पुढे ______ या नावाखाली सुरु झाल्या होत्या.

The correct answer is Option B (Praja Parishad).

Key Points:
• Princely States Movement in Southern Maharashtra:
• The Dakshini Sansthan Hitvardhak Sabha (Southern Princely States Welfare Association) was founded in 1921 at Pune by leaders like G.R. Abhyankar, N.C. Kelkar, and A.V. Patwardhan to demand civil liberties and responsible governance in Deccan states (such as Miraj, Sangli, Jamkhandi, Bhor, and Kolhapur).
• As the All India States Peoples' Conference (AISPC) gained momentum in the late 1920s and 1930s, the localized regional branches of this sabha were re-organized and launched under the title of 'Praja Parishad' (or Praja Mandals) across various princely states.
• These Praja Parishads advocated for constitutional rule, land tax reduction, and the eventual merger of princely states into the Indian Union.
• Key Takeaway: Branches of the Dakshini Sansthan Hitvardhak Sabha functioned across princely states under the name 'Praja Parishad'.
