if the displacement of a body is zero, is the distance covered by it necessarily zero.

Distance is defined as the actual distance traveled by a body irrespective of the direction.
Displacement is defined as the distance between the final and the initial point.
If a body starts from some point, say A, goes in a circle and comes back to point A, then the displacement as defined will be zero. Because the initial and final points will be same and there will be zero distance between them. But in the same case distance will not be zero and will be given by the length of actual path traveled by body.
Hence, displacement can be zero, even if distance covered is non-zero.
