Refer to the following object: 01 const cat = { 02 firstName: 'Fancy', 03 lastName: 'Whiskers', 04 get fullName(){ 05 return this.firstName + ' ' +…

The code defines a getter for the fullName property. A getter binds an object property to a function that is executed when that property is looked up. It is accessed like a standard property, without parentheses, which invokes the underlying function and returns its result. Calling it as a function cat.fullName() would result in a TypeError because the property's value is the string returned by the getter, not the function itself.

A. cat.fullName() attempts to call the property as a method, which is incorrect for a getter and will cause a TypeError.

B. cat.get.fullName is invalid syntax; get is a keyword for defining the accessor, not a property on the object instance.

C. cat.function.fullName() is invalid syntax; function is not a property on the cat object that would contain fullName.
