Correct Answer: Option (D)

Concept & Option Breakdown

Standard Reference Verified

Uniform motion in one dimension is defined by constant velocity ($v = \frac{dx}{dt} = \text{constant}$). On an $x$-$t$ (displacement/distance-time) graph, a constant rate of change is represented by a straight line with constant slope. Graph (d) shows a straight line with constant non-zero slope, representing uniform motion.

Elimination Heuristic & Exam Approach

Slope of $x-t$ graph equals velocity. A straight line graph indicates constant slope, hence uniform velocity.
