Which of the following bodies does not/do not find mention in the Constitution? 1. National Development Council 2. Planning Commission 3. Zonal Councils Select the correct answer using the codes given below.

1. The question asks which of the given bodies are not mentioned in the Constitution of India. 2. The National Development Council (NDC) was established by an executive resolution of the Government of India in August 1952. It is neither a constitutional body nor a statutory body; it is an extra-constitutional advisory body. Therefore, it does not find mention in the Constitution. 3. The Planning Commission was also established by an executive resolution of the Government of India in March 1950. Like the NDC, it was an extra-constitutional, non-statutory advisory body (it has since been replaced by NITI Aayog, which is also extra-constitutional). Therefore, it does not find mention in the Constitution. 4. The Zonal Councils were established by an Act of the Parliament, namely the States Reorganisation Act of 1956. They are statutory bodies created to promote interstate cooperation. Since they are created by a statute (an Act of Parliament) and not by the Constitution itself, they do not find mention in the Constitution. 5. Thus, none of the three bodies – National Development Council, Planning Commission, and Zonal Councils – find mention in the Constitution.
