Refer to the following code block: class Animal{ constructor(name){ this.name = name; } makeSound(){ console.log(`${this.name} is making a sound.`) }…

The code demonstrates class inheritance and method overriding in JavaScript. The Dog class extends the Animal class, inheriting its properties and methods. However, the Dog class provides its own implementation of the makeSound method. When myDog.makeSound() is called on an instance of the Dog class, the JavaScript runtime executes the version of the method defined in the Dog class, not the one in the parent Animal class. This results in the output "Puppy is barking."

B. Puppy is cracking: This is incorrect because the string "cracking" is not defined in the makeSound method of either the Dog or Animal class.
