A class named Actor extends class Movie and both classes have a method called getName $()$ that contains different code. An actor object tomCrui se and a movie object missionImpossible have been created. Assume tomcruise gets assigned to missionImpossible

$($i$.$e$.$ missionImpossible $=$ tomCruise$)$ and we call missionImpossible. getName $(),$ the code inside of the getName $()$ method in the Actor class will be executed

To get a polymorphic operation as described above, which of the following must be true.

$($Select all that apply$)$

The getName$()$ method must be a member of the subclass: Actor

$-$The getName$()$ method must be a member in the superclass: Movie

The superclass and subclass method signatures must be the same

The superclass and subclass method return types must be the same.
