When a body from one point travels to another point and later returns to the original position, then there is (b) zero displacement.
Explanation:
Displacement refers to the change in the position of an object in a particular direction.
It is a vector quantity, that has both magnitude and direction.
Therefore, when the body travels from one point A to point B and then returns to point A, displacement becomes zero.
When the initial and final position of a body is the same, the displacement is said to be zero.

Explanation:
When a body starts at point A and reaches point B in a straight line, and then returns back to point A, the displacement of the body can be determined by calculating the difference between the initial and final positions.
Positive Displacement:
If the final position of the body is ahead of the initial position, i.e., B is located at a greater distance from A, then the displacement is considered to be positive. This means that the body has moved in the forward direction with respect to its initial position.
Negative Displacement:
If the final position of the body is behind the initial position, i.e., B is located at a smaller distance from A, then the displacement is considered to be negative. This means that the body has moved in the backward direction with respect to its initial position.
Zero Displacement:
If the final position of the body is the same as the initial position, i.e., B coincides with A, then the displacement is considered to be zero. This means that the body has not moved from its initial position and has returned back to the same point.
In the given scenario, the body starts at point A, reaches point B, which is ahead in a straight line, and then returns back to point A. Since the final position of the body is the same as the initial position, the displacement is zero. This is because the body has not moved away from its initial position and has returned back to the starting point.
Hence, the correct answer is option 'C' - zero displacement.

The correct answer is C: zero displacement.
Explanation:
- Displacement is the straight line distance between the starting and ending points of an object's motion.
- In this scenario, the body starts at A, goes to B, and then returns to A. Even though the body travels a certain distance (twice the distance between A and B), it ends up back at its starting point (A).
- Since displacement considers the net change in position, and the body ends at the same point it started, the displacement is zero.
