Assertion (A) : The velocity-time graph of a body in motion can be a straight line parallel to the time axis.
Reason (R) : This is because the motion of body is with non-uniform velocity.
- Both A and R are true and R is the correct explanation of A
- Both A and R are true and R is not the correct explanation of A
- Assertion is false but reason is true
- Assertion is true but reason is false

Answer
Assertion is true but reason is false
Explanation
Assertion (A) is true because a straight line parallel to the time (x) axis implies same velocity at all times so this happens when the velocity remains constant over time, i.e., uniform velocity.
Reason (R) is false because a horizontal velocity-time graph (parallel to the time axis) indicates uniform velocity not non-uniform velocity which shows the velocity doesn’t change with time.
Hence, assertion is true but reason is false.
