E) If assertion is false but reason is true.
Correct Answer: C
Solution :
In uniform motion the object moves with uniform velocity, the magnitude of its velocity at different instant i.e. at t = 0, t = 1sec, t = 2sec,.... will always be constant. Thus velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to time axis.
