UPSC 2025: Consider the following pairs: State : Description 1. Arunachal Pradesh : Shares international boundary with three countries 2. Meghalaya : Has the shortest international boundary with Bangladesh among the north-eastern States 3. Mizoram : Shares international boundary with two countries How many of the above pairs are correctly matched?

Arunachal Pradesh does not have a district named after its capital Itanagar, although it does contain two national parks (Namdapha and Mouling); hence pair I is not correctly matched. Nagaland became a state through the Constitution (13th Amendment) Act, 1962, so pair II is correct. Tripura was made a Union Territory in 1956 and later attained full statehood on 21 January 1972 under the North-Eastern Areas (Reorganisation) Act, thus pair III is correct. Therefore two pairs are correctly matched. ([en.wikipedia.org](https://en.wikipedia.org/wiki/List_of_districts_of_Arunachal_Pradesh?utm_source=openai))
