A body at rest can have 

A body at rest can have PE

Potential Energy: The Energy possessed by a body by virtue of its position (or) configuration is called PE so option (D) is correct conclusion

Where A, B, C are incorrect because

Kinetic Energy – by virtue of motion so, it will not present when a body is at rest.

Momentum (P) – Mass × velocity [At Rest u = 0]

So P = 0
