India recently signed a landmark Land Boundary Agreement to settle long pending border and enclave issues with which of its neighbouring countries?

Introduction / Context:
India shares land borders with several neighbouring countries, and in some cases historical boundary issues created enclaves and complex territorial arrangements. A significant diplomatic achievement was the Land Boundary Agreement that aimed to resolve such issues with one neighbour by exchanging enclaves and simplifying the border. This question asks the learner to identify that country as Bangladesh.

Given Data / Assumptions:

• The question refers to a Land Boundary Agreement signed by India.
• The purpose was to settle long pending border and enclave issues.
• The options include several countries that share borders with India.
• Only one of these is linked with the specific Land Boundary Agreement mentioned in recent affairs.

Concept / Approach:
The approach is to connect the phrase Land Boundary Agreement with the correct neighbour. India and Bangladesh had a complicated border with enclaves, adverse possessions, and small pockets of land inside each other territory. The agreement permitted exchange of these enclaves, clarified the boundary, and improved local governance. China, Nepal, Bhutan, and Myanmar have their own boundary arrangements, but the specific Land Boundary Agreement widely reported in recent years involves Bangladesh.

Step-by-Step Solution:
Step 1: Recall which neighbouring country had numerous enclaves inside India and vice versa.Step 2: Remember that India and Bangladesh signed a comprehensive Land Boundary Agreement to exchange these enclaves.Step 3: Note that the agreement required constitutional amendment and ratification.Step 4: Compare this context with the options and identify Bangladesh as the relevant neighbour.Step 5: Choose Bangladesh as the correct answer.

Verification / Alternative check:
Reviewing recent international relations summaries shows that the India Bangladesh Land Boundary Agreement was considered a major achievement in bilateral ties. It is regularly cited in exam materials as an example of successful boundary settlement. None of the other options is associated with an agreement using the same title and features, which confirms Bangladesh as correct.

Why Other Options Are Wrong:
Option A: China has unresolved boundary disputes with India but not this specific Land Boundary Agreement regarding enclaves.Option B: Nepal shares an open border with India, and current issues are different in nature.Option C: Bhutan has cordial boundary ties, and no such enclave based Land Boundary Agreement has this profile.Option E: Myanmar shares a border with India but is not part of this particular agreement.

Common Pitfalls:
Learners may confuse different boundary topics, such as Line of Actual Control with China, open border issues with Nepal, or general border management with Myanmar. The distinct clue in this question is the mention of enclaves and a formal Land Boundary Agreement, which clearly points to Bangladesh. Remembering this association helps avoid misidentification.

Final Answer:
The correct answer is Bangladesh.
