खालीलपैकी कोणते/कोणती विधान/विधाने बरोबर नाही/त?
(a) 15 ऑगस्ट 1999 रोजी परभणी जिल्ह्याचे विभाजन झाले.
(b) हिंगोली कयाधू नदीच्या किनाऱ्यावर वसले आहे.
(c) वसमत तालुका परभणी जिल्ह्यात आहे.

The correct answer is Option C (Statements (a) and (c)).

Key Points:
• Political and Administrative Geography of Maharashtra (Hingoli & Parbhani):
• Bifurcation of Parbhani: Statement (a) is incorrect. Hingoli district was carved out of Parbhani on 1st May 1999 (Maharashtra Day), NOT on 15th August 1999 (Gondia was formed from Bhandara on 1st May 1999, while Nandurbar and Washim were created on 1st July 1998).
• Kayadhu River: Statement (b) is correct. Hingoli town is situated on the banks of the Kayadhu River (a prominent tributary of the Painganga).
• Vasmat Tahsil: Statement (c) is incorrect. Vasmat (Basmath) tahsil is part of the newly created Hingoli district, NOT Parbhani district (Hingoli has 5 talukas: Hingoli, Kalamnuri, Vasmat, Aundha Nagnath, Sengaon).
• Statements (a) and (c) are incorrect (Option 3).
• Key Takeaway: Parbhani was bifurcated on 1 May 1999 to create Hingoli (which contains Vasmat tahsil and lies on Kayadhu river).
