Since the function exists within the Person class, it already has access to the private member variables. Therefore, the correct way to output the data is to directly reference the private variables within the function using the variable names (i.e. age, weight, id). Option A is incorrect because it references the object "person" which is not defined within the function. Option B is incorrect because it would require overloading the << operator for the Person class, which is not given in the problem statement. Option D is not a valid option as it does not provide any code to output the private data.
