The correct answer is (a) Article 243 ZD.
Article 243 ZD of the Constitution of India provides for the establishment of District Planning Committees in every district. The Committees are responsible for preparing a draft development plan for the district and for coordinating the implementation of the plans prepared by the Panchayats and Municipalities in the district.
Article 362 deals with the power of the President to suspend the operation of the Constitution in certain areas. Article 356 deals with the President’s power to proclaim President’s Rule in a State. Article 368 deals with the amendment of the Constitution.
Article 243 ZD is the most relevant article for the question as it specifically deals with the establishment of District Planning Committees. The other articles are not relevant as they do not deal with the subject of the question.
