A copy constructor creates a new object by initializing it with an existing object of the same type. Therefore, the parameter of the copy constructor should be a reference to an object of the same class (option C). Option A is not preferred because it would involve creating a copy of the parameter within the body of the function, which defeats the purpose of the copy constructor. Option B is incorrect because it suggests passing in an object of a different class, which is not a copy constructor. Option D is not a valid option in C++, as there is no call-by-name parameter passing mechanism.
