A. true (yes). Because when momentum zero k.e zero but p.e is not zero

if it's momentum is zero then it's velocity would be zero hence the object will be at rest
but mechanical energy is sum of kinetic energy and potential energy
as kinetic energy depends on velocity so kinetic energy will become zero but potential energy does not depend on velocity
P.E=MGH
so it will have potential energy
hence the answer is option A
