when distance is zero then the displacement must be zero .
because, distance is a scalar quantity and does not depends on direction so it never be negative
and when distance become zero that means you are in rest only. so the displacement is also zero.
But,
when the displacement is zero then the distance may or may not be zero .
because, displacement is a vector quantity and it may be negative or positive it depends upon the direction.
for e.g. if you move north 5km and then turn back and move south 5km, here if you take north as negative and south as positive then there is zero displacement (+5-5 = 0) . however, the distance you covered is (5+5)=10km
so here displacement is zero but distance is non zero.
I hope you got it .....

Answer:
No, it is not possible that a body has zero distance but non zero displacement. Distance cannot be zero because distance is the total path covered but displacement is the shortest route taken to cover the distance. So distance is always greater than displacement.
