Explanation: India and Bangladesh share a long and porous border, which has historically facilitated the movement of people across the border. This movement has been driven by various factors, including economic opportunities, political instability, and natural disasters. The issue of illegal immigration from Bangladesh to India has been a significant concern for the Indian government, as it has led to demographic changes in certain regions, particularly in the northeastern states of India.
The problem of illegal immigration has been exacerbated by the lack of effective border management and the absence of a comprehensive legal framework to address the issue. India has attempted to tackle this problem through various measures, including the construction of a border fence and the implementation of the National Register of Citizens (NRC) in Assam, which aims to identify and deport illegal immigrants.
The issue of illegal immigration from Bangladesh has also been a point of contention in bilateral relations between India and Bangladesh. India has raised the issue at various international forums and has sought cooperation from Bangladesh to address the problem. The Indian government has filed complaints with international bodies, including the United Nations, to highlight the issue and seek a resolution.
It is important to note that the issue of illegal immigration is complex and multifaceted, involving economic, social, and political dimensions. The solution to this problem requires a comprehensive approach that addresses the root causes of migration and involves cooperation between the two countries to manage the border effectively.
In summary, the correct answer is Bangladesh because it is the country with which India has significant issues related to illegal immigration, and India has filed complaints against Bangladesh to address this problem. The other options (Sri Lanka, Pakistan, and Maldives) do not share the same level of illegal immigration issues with India, making them incorrect choices.
