Solution

The statement that is true regarding polymorphism is: "An overridden method can be less restrictive than the superclass method".

Here's why:

  1. An overridden method can be less restrictive than the superclass method: This is true. In Java, if a superclass method is declared protected, its subclass overridden method can have a more accessible modifier like public, but not a less accessible one like private.

  2. An overridden method can be more restrictive than the superclass method: This is false. As explained above, an overridden method in a subclass cannot have a more restrictive access modifier than the method in the superclass.

  3. Overloaded methods cannot change the return type: This is false. Overloaded methods can change the return type. Overloading is about having methods with the same name but different parameters in the same class. The return type doesn't factor into this.

  4. Constructors can be overridden: This is false. In Java, constructors are not inherited by subclasses so they cannot be overridden.

If a method defined in a subclass is private in its superclass, the two methods are completely unrelated.A static method cannot be overridden. If a static method defined in the superclass is redefined in a subclass, the method defined in the superclass is hidden.
