Consider the following Java Interface:
interface Pet{
void play();
} Suppose we want to code the Dog class, which is not an abstract class, and implement the pet interface. Which of the following actions needs to be performed in the given scenario? Choose the best options: A) Declare the Dog class to extend the Pet interface and override the abstract method play. B) State "Dog implements Pet" in the class declaration. The play method is automatically inherited from the pet interface. C) State "Dog implements Pet" in the class declaration and provides an implementation for the play method in the code of Dog class. D) Implement the play method in the Dog class. The Java compiler automatically deduces that the class Dog implements the corresponding interface.
