The correct answer is Option B (front of the authority mentioned by the law.).

Key Points:
• Election disputes and challenges regarding municipal and panchayat elections are strictly regulated by state municipal corporation acts and local government laws.
• Legal procedure:
• An election petition challenging the outcome or validity of an elected municipal candidate cannot be filed arbitrarily in any regular court or directly before the Election Commission once results are declared; it must be presented before the designated judicial authority or tribunal specifically prescribed and empowered by the relevant State Municipal Act (such as the District Judge or designated civil court acting as the statutory authority).
• Therefore, an election is challenged before the authority specified and provided by law (Option 2).
• Key Takeaway: Municipal election challenges and petitions must be brought before the specific judicial authority designated by state municipal law.
