UGC NET Questions (Paper – 1)

Statements A, B, C and D represent correct principles for direction-sense reasoning. A is true since the four main directions are treated as perpendicular axes. B and C correctly describe standard right and left turns from given orientations. D is correct because many questions reduce movements to net north–south and east–west components, often using coordinate or vector-like thinking. E is false because “left of B” depends on B’s facing direction, not necessarily on the geographic west, so A, B, C and D only are correct.

Option A:
Option A is incomplete because although A, B and C are true, it omits D, which explains how to compute final displacement using perpendicular components, a key exam technique.

Option B:
Option B is incorrect as it includes E, which wrongly interprets “left” as fixed west, and thus mixes one false statement with true ones. This invalidates the combination.

Option C:
Option C is wrong since it drops A and includes only B, C and D, failing to mention the fundamental assumption about the four perpendicular directions that underlies most diagrams.

Option D:
Option D is correct because it collects all four true statements about directions and turning, while excluding E, which confuses relative and absolute positions. It matches how NET questions on direction sense are structured.

Statements A and B correctly describe basic facts about directions and displacement, and D is true because right-triangle paths allow the use of Pythagoras theorem to compute straight-line distance. Statement C is false since turning right from north leads to east, not west, and E is false because direction sense can be interpreted through coordinate geometry and vector concepts, making it quite related. Therefore, the set A, B and D only is correct.

Option A:
Option A is incomplete as it omits D and thus misses the important connection between direction sense paths and right-triangle geometry, which is central in many distance questions.

Option B:
Option B is correct because it includes all three true statements and excludes C and E, both of which misstate directional relationships or conceptual links. It accurately reflects how NET-level direction questions combine basic orientation with simple geometry.

Option C:
Option C is wrong since it includes C, the incorrect turning rule, and leaves out A, failing to mention the fundamental opposition of cardinal directions. This combination is therefore not acceptable.

Option D:
Option D is incorrect because it includes C and excludes B, thereby mixing an incorrect turning direction with a partial description of displacement and Pythagorean use.
