Environmental migration and displacement – UGC NET Question

Statements A, C and D are correct as they acknowledge that environmental degradation and both sudden- and slow-onset changes can drive migration, that displacement has multiple consequences and that planned relocation is a possible adaptation response. Statement B is incorrect because slow-onset processes like sea-level rise or desertification do influence migration decisions in many regions. Therefore, the combination that selects A, C and D only is correct.

Option A:
Option A is incorrect because it omits statement D, even though D accurately notes planned relocation as an adaptation option in some high-risk areas. Leaving out D means the answer does not capture the full set of correct statements.

Option B:
Option B is correct because it includes all three true statements while excluding B, which wrongly restricts migration drivers to only sudden-onset disasters. It reflects the broader understanding of environmental migration used in this unit.

Option C:
Option C is incorrect since it accepts B as correct along with C and D. Although C and D are true, B is false, and a combination containing a wrong statement cannot be considered correct.

Option D:
Option D is incorrect as it claims that all four statements are correct. Because B is clearly false, treating it as true makes the entire combination unacceptable.
