Explanation
The Planning Commission of India has been replaced by Niti Ayog.
The Planning Commission was an institution in India responsible for formulating five-year plans for economic development and social welfare. It was established in 1950 and functioned as an extra-constitutional body. However, in 2015, the government of India announced that it would be replaced by a new institution called Niti Ayog.
Niti Ayog, also known as the National Institution for Transforming India, is a policy think-tank established in 2015 to replace the Planning Commission. Unlike the Planning Commission, which had a top-down approach to economic planning, Niti Ayog aims to involve state governments and other stakeholders in the policy-making process. The institution's mandate includes formulating national development plans, promoting cooperative federalism, and conducting research on policy issues.
Thus, the correct answer to the question is A: Niti Ayog.
