Refer to the following object:const dog = { firstName: ' Beau ' , lastName: '...

The correct answer is A .

This object uses a getter :

get fullName() {

return this.firstName + ' ' + this.lastName;

}

A getter looks like a method when it is defined, but it is accessed like a normal property.

So the correct access syntax is:

dog.fullName

That returns:

" Beau Boo "

The important distinction is:

dog.fullName

not:

dog.fullName()

Because fullName is a getter property, not a regular function property.

Option B is incorrect because calling dog.fullName() tries to call the returned string as a function. Since " Beau Boo " is not a function, that would cause a TypeError.

Option C is incorrect because there is no get object inside dog.

Option D is incorrect because there is no function object inside dog, and getters are not accessed that way.

Therefore, the verified answer is A .
