Due to the polymorphism rules in C$++,$ if a subclass named x has its superclass, named y$,$ and both classes have different public methods defined as void printAll$(),$ which of the methods will be executed when an object named o of the class x has the command:

o$.$printAll$()$;

Due to the polymorphism rules in C$++,$ if a subclass named x has its superclass, named y$,$ and both classes have different public methods defined as void printAll$(),$ which of the methods will be executed when an object named o of the class x has the command:

o$.$printAll$()$;

The method printAll$()$ of the class x will be executed.

The method printAll$()$ of the class with fewer methods will be executed.

The method printAll$()$ of the class y will be executed.

The method printAll$()$ of the class with fewer instance variables will be executed.
