How many Indian states share an international land border with Myanmar?

Introduction / Context:
India shares land borders with several neighbouring countries, including Myanmar to the east. Knowing which and how many Indian states touch these borders is an important part of political geography. Exam questions frequently ask about the number of states sharing borders with a specific country, and in the case of Myanmar, the count is four northeastern and eastern states.

Given Data / Assumptions:

• The question asks for the number of Indian states that share a border with Myanmar.
• The numerical options are 6, 7, 3, and 4.
• We assume current standard political boundaries and that union territories are counted separately from states.
• We need to list the relevant states and count them accurately.

Concept / Approach:
The concept here is simple counting based on map knowledge. Myanmar lies to the east of India and shares frontiers with four Indian states: Arunachal Pradesh, Nagaland, Manipur, and Mizoram. No other Indian states share a land border with Myanmar. Therefore, after identifying and counting these four, we can select the option that matches this number.

Step-by-Step Solution:
Step 1: Look at the northeastern map of India and identify the Indian states that physically touch the boundary with Myanmar.Step 2: Note that Arunachal Pradesh in the far northeast shares a border with both China and Myanmar.Step 3: Recognise that Nagaland lies to the south of Arunachal Pradesh and also touches Myanmar.Step 4: Remember that Manipur and Mizoram further south both share borders with Myanmar as well.Step 5: Count these states: Arunachal Pradesh, Nagaland, Manipur, and Mizoram, giving a total of four states.

Verification / Alternative check:
An atlas or political map of India clearly shows the India Myanmar border stretching along the eastern side of these four states. No other state beyond these has its boundary touching Myanmar. Tripura, Meghalaya, and Assam are adjacent to Bangladesh, and Sikkim borders Nepal, Bhutan, and China, not Myanmar. This visual check supports the conclusion that exactly four Indian states share a boundary with Myanmar.

Why Other Options Are Wrong:
6: This would require additional states on the Myanmar border, but only four states actually touch that boundary.
7: This is even higher than 6 and is not supported by the map; several northeastern states border Bangladesh, Bhutan, or China instead.
3: This option undercounts the border states and typically results from forgetting one of the four, often Mizoram.

Common Pitfalls:
Students sometimes confuse the India Myanmar border with the India Bangladesh border or mix up which northeastern states lie where. Another common mistake is to assume that all or most of the northeastern states border Myanmar, leading to overestimates like 6 or 7. To avoid errors, it is useful to remember a simple list of four: Arunachal Pradesh, Nagaland, Manipur, and Mizoram, and then mentally verify them on a map.

Final Answer:
India shares its land border with Myanmar through 4 states: Arunachal Pradesh, Nagaland, Manipur, and Mizoram.
