Bangladesh shares its international border with several Indian states. Which one of the following states does Bangladesh not share a boundary with?

Introduction / Context:
The international boundary between India and Bangladesh is long and complex, touching several Indian states. Exam questions frequently ask which states share this border and which do not, to test detailed knowledge of political and physical geography in eastern India.

Given Data / Assumptions:

• The country of interest is Bangladesh on India's eastern side.
• The options are Assam, Tripura, Jharkhand, and Meghalaya.
• We assume the learner has seen a political map of eastern and north eastern India.

Concept / Approach:
Bangladesh shares its border with the Indian states of West Bengal, Assam, Meghalaya, Tripura, and Mizoram. It does not share a boundary with Jharkhand. Jharkhand is an inland state located to the west of West Bengal and does not directly touch the Bangladesh border. Assam, Tripura, and Meghalaya all have sections of international boundary with Bangladesh, especially around the Sylhet and Chittagong regions of that country.

Step-by-Step Solution:
Step 1: Recall or visualise the map of Bangladesh and the adjoining Indian states. Step 2: Note that West Bengal surrounds Bangladesh on the west, while Assam, Meghalaya, Tripura, and Mizoram lie to the north and east. Step 3: Check each option: Assam borders Bangladesh along its southern districts, Tripura is almost surrounded on three sides by Bangladesh, and Meghalaya has a long border to the south with Bangladesh. Step 4: Observe that Jharkhand lies inland, west of West Bengal, and does not intersect the Bangladesh boundary. Step 5: Conclude that Jharkhand is the state that does not share a border with Bangladesh.

Verification / Alternative check:
A political map of India and Bangladesh clearly shows border lines between Bangladesh and West Bengal, Assam, Meghalaya, Tripura, and Mizoram only. Jharkhand appears further to the west without any direct contact with Bangladesh. This graphical evidence confirms that Jharkhand does not share an international border with Bangladesh.

Why Other Options Are Wrong:

• Assam: Shares a segment of border with Bangladesh, especially near the Barak Valley and adjoining areas.
• Tripura: Almost surrounded by Bangladesh on three sides, with a long international boundary.
• Meghalaya: Bounded by Bangladesh to the south along much of its length.

Common Pitfalls:
Learners sometimes confuse inland states near the east such as Jharkhand or Bihar with those that actually touch the Bangladesh border. Another common error is to rely only on memory of one or two bordering states like West Bengal and forget others such as Meghalaya and Mizoram, making it harder to identify which state is excluded. Regular practice with political maps helps fix these details in memory.

Final Answer:
Among the given options, Jharkhand is the only Indian state that does not share a border with Bangladesh.
