The correct option is 1 only because the National Green Tribunal Act, 2010 was specifically enacted to provide a dedicated mechanism for the enforcement of environmental laws, reinforcing the principle that the right to a healthy environment is inherent to the Right to Life as guaranteed by Article 21 of the Constitution of India. This aligns with judicial interpretations acknowledging environmental protection as a fundamental aspect of an individual’s right to life, ensuring that citizens can live in a safe and healthy environment. Options 2 and 3 do not directly relate to the scope or purpose of the National Green Tribunal Act, which is solely focused on environmental governance rather than the welfare of Scheduled Tribes or the functions of the Gram Sabha.
