Linear and circular seating logic – UGC NET Question

Statements A, B and C all describe essential features of seating puzzles. A is correct because in a row, left and right depend on the facing direction. B is correct as neighbours in a circle facing the centre are those immediately adjacent along the circumference. C is also true; when people face outward, the sense of left and right relative to the circle reverses compared to facing inward. D is false because assuming a common facing direction without explicit information can lead to wrong conclusions. Thus, A, B and C only are correct.

Option A:
Option A is incomplete because it lists only A and B and omits C, which explains the reversal of left and right when people face outward. Without C, understanding of circular arrangements is incomplete.

Option B:
Option B is correct as it collects all three true statements about orientation and neighbouring positions and excludes D, which would lead to improper assumptions in exam questions. It matches the conventions of NET seating arrangement problems.

Option C:
Option C is incorrect since it omits A and includes only B and C, losing the basic rule about left and right in linear arrangements, which are also commonly tested. This makes the option partial.

Option D:
Option D is wrong because it contains D, which incorrectly permits assumptions about facing directions, and omits B, so it both introduces error and drops a central property of circular seating.
