Madhya Pradesh State was constituted on–

Correct option is D

Sol. Madhya Pradesh was officially formed on 1st November, 1956 under the States Reorganization Act, 1956. This act reorganized Indian states based on linguistic and administrative lines. MP was formed by merging the regions of Madhya Bharat, Vindhya Pradesh, Bhopal, and parts of Central Provinces and Berar. It became the largest state by area until Chhattisgarh was carved out in 2000. The state celebrates MP Foundation Day every year on 1st November with parades and cultural programs. The reorganization brought administrative unity and improved governance.
Explanation of each option:
· (a) 1959 – Incorrect; no significant state reorganization occurred in MP this year. Foundation had already happened in 1956.
· (b) 1958 – By this year, MP was already functioning as a consolidated state; not the formation year.
· (c) 1957 – Wrong again; this year was post-formation and had no special significance in state reconstitution.
· (d) 1956 – Correct answer. Official formation year under States Reorganisation Act, marking the political birth of modern MP.
