When one method calls another, which of the following statements are true?

I. The class methods and instance methods of one class may call the public class methods of another class using dot notation and referencing the name of the other class.
II. The class methods and instance methods of one class may call the private instance methods of another class by using dot notation to invoke the method on an instance of the other class.
III. The instance methods of a class may call, without using dot notation, any class method of the same class.

I. The class methods and instance methods of one class may call the public class methods of another class using dot notation and referencing the name of the other class.

Explanation:

Private methods are being accessed from only within the class or scope specified. No other means of accessibility is possible, and even through inheritance. And instance methods can never call without using dot notation, any of the class method of the same class. Hence second and third options are not correct. And the class method and the instance methods of one class may call the public class methods of another class using the dot notation and referencing the name of the other class. Hence, the correct option is the first one.
