Which of the following graphs are straight lines?
A. Distance – time graph of a body at rest
B. Velocity – time graph of a body moving with uniform acceleration
C. Distance – time graph of a body moving with uniform acceleration
D. Velocity – time graph of a body at rest
Choose the correct option:

Correct option is D

The correct answer is A, B and D.
A. Distance – time graph of a body at rest:
This graph would be a straight horizontal line at the distance axis, showing that the body is not changing its position over time.
B. Velocity – time graph of a body moving with uniform acceleration:
This graph would be a straight line inclined upwards or downwards, indicating a constant change in velocity over time due to uniform acceleration.
C. Distance – time graph of a body moving with uniform acceleration:
This graph would be a curve, not a straight line. The slope of the curve would change, indicating the changing velocity due to uniform acceleration.
D. Velocity – time graph of a body at rest:
This graph would be a straight horizontal line at the velocity axis, showing that the body’s velocity remains constant over time.
