NITI Aayog

The correct answer is Option (4) - NITI Aayog

In 2015, the Planning Commission was replaced with the NITI Aayog (National Institution for Transforming India). The government of India decided to disband the Planning Commission and replace it with a new institution called NITI Aayog (National Institution for Transforming India). The decision to replace the Planning Commission with NITI Aayog was driven by the need for a more modern, flexible, and responsive institution that could better address the challenges of India's rapidly evolving economy and development landscape.

NITI Aayog was established with the aim of fostering cooperative federalism, promoting sustainable and inclusive growth, and catalyzing transformative reforms across various sectors. Unlike the Planning Commission, which operated as a centralized planning body, NITI Aayog functions as a think tank and policy advisory body, providing strategic advice and recommendations to the government on economic and social issues.
