Displacement is the shortest length between the initial point and the final point of a body in motion. So it is different from distance...
Case 1.
The body doesn't change its position. So it is at rest. Hence displacement = distance =0
Case 2.
The body is in a round trip, Where the body moves back to its initial position. Hence distance>displacement.
So option 4 is the correct answer...
