The numerical ratio of displacement to distance is:
A
Always less than one
B
Always equal to one
C
Always greater than one
D
Equal to or less than one
Correct Answer: Option D — Equal to or less than one

Equal to or less than one follows directly from the definitions and relationships used in kinematics. The question tests whether the learner...
Equal to or less than one follows directly from the definitions and relationships used in kinematics. The question tests whether the learner can distinguish the required quantity from related ideas and use the stated information without adding unsupported assumptions. The alternatives Always less than one, Always equal to one, and Always greater than one do not satisfy the governing definition, graph interpretation, direction convention, or numerical relationship in this case. In examinations, identify the known quantities, keep SI units consistent, select a positive direction where needed, and apply the appropriate definition or equation. This also checks that the answer has a sensible magnitude and unit.
