Average Velocity and Average Speed is same for :
Both option A and C.
For average velocity and average speed to be same, distance and displacement of the body should be same. A flight travels in almost the least minimum distance between initial and final position. So, its distance and displacement are approximately same. If a car is making a round trip on a circular track, its displacement will be 0, whereas it will have some non-zero value for distance covered. On a straight road, distance and displacements are same as long as the object never returns back and always moves along the same direction.
