                        Which of the following statements correctly explains the use of instanceof and type hinting?
Each correct answer represents a complete solution (Choose three).                    

                    


                    

                                                                    

                    

                    


                    
                                            


                
                


                A)  The instanceof operator lets a programmer inspect all of the ancestor classes of the object, as well as any interfaces.                    
                    
                    
                                    

                B)  Type hinting is a feature due to which functions can specify what type of parameters must be provided to the functions.                    
                    
                    
                                    

                C)  The instanceof operator can be used to check if the variables are the member of an abstract class.                    
                    
                    
                                    

                D)  The instanceof operator can be used to check if the variables are an instance of a particular class.
