Option 1: NITI Aayog does indeed provide critical direction and strategic input for the development process. This means that it helps in guiding and shaping the overall direction and strategy for the country`s development.
Option 2: NITI Aayog also functions as a `think tank`, which means it provides key elements of policy. It conducts research, analysis, and provides recommendations on various issues to the government.
Option 3: NITI Aayog is responsible for monitoring and evaluating the implementation of various government programs. This means that it assesses the progress and effectiveness of these programs and provides suggestions for improvement.
Option 4: This option is the correct answer. NITI Aayog does not offer a platform for the resolution of inter-state conflicts as a `provider of first and last resort`. It is primarily focused on providing policy inputs, strategic direction, and monitoring the implementation of programs for the development of the country.
