Ans. D

Sol.

The shortest distance between initial point and final point is called displacement and total path length is called distance.

If a particle travels in a straight line without turning back, then its distance and displacement will be equal. In all other cases distance will be more than  or equal to displacement.

Therefore, the ratio of displacement and distance will be equal or less than 1

Hence the correct option is D.
