Strategy for arrangement puzzles – UGC NET Question

The only wrong statement here is C; all of A, B, D and E are correct. Effective puzzle solving relies on diagrams and on respecting every given constraint, and some questions explore what is true in all valid arrangements. Random guessing and ignoring constraints is neither efficient nor recommended.

Option A:
Option A is incorrect because it treats both B and C as wrong, even though B is a sound reminder about using all constraints to avoid contradictions.

Option B:
Option B is wrong since it misclassifies A (diagramming) as wrong, even though it is correct.

Option C:
Option C is correct because it singles out C as the lone incorrect statement.

Option D:
Option D is incorrect because it includes D among wrong statements, even though D correctly notes multiple possible arrangements and “true in all cases” questions.
