To discourage illegal immigration, Assam has strengthened:

Border security
Surveillance measures
Enforcement of citizenship laws
All of the above

The correct answer is: d) All of the above

Assam has strengthened border security, surveillance measures, and enforcement of citizenship laws to discourage illegal immigration.

  • Border security has been strengthened by building fences, installing CCTV cameras, and deploying more security personnel.
  • Surveillance measures have been strengthened by using drones and satellites to monitor the border.
  • Enforcement of citizenship laws has been strengthened by conducting raids and arresting illegal immigrants.

These measures have been effective in reducing illegal immigration into Assam. However, the problem of illegal immigration is still a major challenge for the state.
