The correct answer is option-4, the 74th Constitutional Amendment. The Nagarpalika Bill, also known as the Municipalities Bill, was passed through the 74th Constitutional Amendment. This amendment was introduced in 1992 and aimed to strengthen local self-governance in urban areas. It gave constitutional status to the municipalities and mandated the establishment of elected municipal bodies known as Nagar Palikas. These bodies have the power to govern and manage the affairs of the urban local bodies. The 74th Amendment also laid down provisions for devolving powers and functions to these bodies, ensuring their financial independence, and promoting decentralization in urban governance. It aimed to enhance urban planning, infrastructure development, and overall effective administration in urban areas.
