Q. Consider the following states:

1. Arunachal Pradesh
2. Mizoram
3. Manipur
4. Nagaland

Which of the following sequences represents these states in order of their decreasing share in the length of India’s international border with Myanmar?
Answer: 1 2 3 4
Notes: Arunachal Pradesh shares the longest border with Myanmar (520 km), followed by Mizoram (510 km), Manipur (398 km), and Nagaland (258 km). Therefore, the correct descending order by border length is: Arunachal Pradesh > Mizoram > Manipur > Nagaland, justifying the sequence in option 4.
