Detailed explanation-1: -The correct answer is A curved line. The bodies had uniform motion, their velocity does not change to time. So, the bodies have uniformly accelerated motion. The distance-time graph for a uniformly accelerated motion looks curve.

Detailed explanation-2: -The distance-time graph for a body in non-uniform motion is a curved line.

Detailed explanation-3: -In accelerated motion the distance time graph is not a straight line. The graph is parabola when there is a uniform accelerated motion and Graph is irregular when there is non-uniform acceleration. For a body to undergo an accelerated motion, the velocity time graph is a straight line.

Detailed explanation-4: -A curved graph with a positive slope represents a positive acceleration, while a negative slope represents a negative acceleration. The steeper the slope, the greater the acceleration, while a flatter slope represents a smaller acceleration.

Detailed explanation-5: -A distance–time graph shows the total distance traveled by an object on the vertical axis and time on the horizontal axis. A straight horizontal line means the object is stationary. A straight sloped line means the object is moving at a constant speed. A curved line means the object is accelerating.
