Question

Is it possible that displacement is zero but not the distance. Under wha
condition displacement will be equal to distance.

Answer 1

when the final position is same as the starting position (that is the initial position) then the displacement Willbe zero. for example if we took a circular track if it's starting position and the final position are same then the displacement will be zero

Answer 2

It can be possible that displacement is Zero

If a body covers a certain distance and comes back to the initial position

If a body covers a certain distance in a straight line path then distance will be equal to displacement
