Correct option is C
The correct answer is (c) 1950
Explanation:
The state was officially renamed from the United Provinces to Uttar Pradesh on January 24, 1950.
This change occurred just two days before India became a Republic with the adoption of the Constitution.
The order for the name change was passed by the then Governor-General of India, acting on a request from the provincial legislature.
January 24 is now celebrated annually as 'Uttar Pradesh Diwas' (UP Day) to commemorate this event.
According to NCERT Class 12 (Political Science), the reorganization of states was a continuous process post-independence, and UP was one of the first major provinces to receive a new nomenclature.
