BSF Sundarbans border fencing sequence

Arrange the following events related to the BSF's Sundarbans border fencing project in chronological order:

  1. West Bengal transferred over 1,024 acres of land across nine districts to the BSF.
  2. Sheikh Hasina's government in Bangladesh was ousted, heightening border security concerns.
  3. BSF Director-General Praveen Kumar conducted an on-ground inspection of the Sundarbans fencing progress.
  4. The BSF began a feasibility and technical study to fence roughly 90 kilometres of the Sundarbans border.

Select the correct order:

A2 - 1 - 4 - 3
B1 - 2 - 4 - 3
C2 - 4 - 1 - 3
D4 - 2 - 1 - 3

Tests the ability to reconstruct a causal and chronological sequence across multiple linked events, rather than recalling any single fact in isolation - a higher-order analytical skill.

About this question

Why in news

BSF Director-General Praveen Kumar inspected the Sundarbans from July 11-14, 2026, reviewing the feasibility study to fence roughly 90 km of previously unfenced, ecologically sensitive border terrain.

Why for UPSC

UPSC's 2016 GS3 question on border management challenges shows sustained interest in this theme; this chronology format tests whether aspirants can correctly sequence the causal chain of political trigger, administrative enablement and technical execution, rather than just recalling isolated facts.

Prelims summary

The August 2024 Bangladesh political change heightened security concerns, followed by West Bengal's land transfer to the BSF, which enabled the feasibility study for fencing 90 km of Sundarbans border, reviewed during DG Praveen Kumar's July 2026 inspection.
