Which one of the following Indian states does not share international border with two or more countries?

Based on the geographical distribution of India's international boundaries, Arunachal Pradesh shares borders with three countries: Bhutan, China, and Myanmar. Assam shares international borders with two countries: Bhutan and Bangladesh. Mizoram also shares borders with two countries: Myanmar and Bangladesh. In contrast, Tripura is surrounded by Bangladesh on three sides but shares its international border exclusively with Bangladesh. While Tripura has a long international boundary, it does not meet the criteria of sharing borders with two or more distinct foreign nations. Other states like West Bengal and Sikkim also share borders with three countries, whereas Nagaland and Meghalaya share borders with only one. Therefore, among the given options, Tripura is the only state that does not share an international border with two or more countries.
