in c++

Which of the following statements should be true about copy constructors? Select one or more: a. A user-defined copy constructor is always inherited by a derived class, even if it is overridden. b. A class may have only a single copy constructor c. A copy constructor takes a reference to the object being copied as its parameter 1. If a copy constructor is defined in class Truck, and an instance of Truck is passed to a method that takes an argument of type Truck, the method creates a new instance of Truck by calling the copy constructor, and any changes made to the new instance within the method will not affect the original instance e. The purpose of a copy constructor is to create a new instance of a class that is an exact copy of an existing instance. The new instance is generated by copying the data members of the existing instance f. If an instance of the class Shape, using the default copy constructor, is passed to a method that takes arguments Shape biff and that method changes biff internally, then the original instance will be changed g. The default copy constructor identifies dynamically allocated memory and re-allocates the same amount of memory for the new instance
