If you have the following class definitions,which of the following is the proper way to construct an object of the derived class? Class Pet { Public: Pet); Void printPet); String getName); Void setNamestring newName); Private: String name; }; Class Dog:public Pet { Public: Dog); Void printPet); Void setTypestring newType); String getType); Private: String type; };

An object of a derived class can be stored in a base class variable
