• A) Rest and motion are defined on basis of position of an object. So a body may be in rest and in the motion at the same time

B) Object is in rest or in motion depends on the reference point. An object may be in motion with respect to a reference point and at same time the object may be in rest with respect to another reference point.

C) Rotatory motion justifies the above statement. In the rotatory motion, object rotates around a fixed axis and does not cover distance. Therefore, object is in motion and in the rest at the same time.

D) No, it is not possible that an object is in the motion and in the rest as well.
