Answer:
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.

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.
The primary function of a fan in a computer system is to cool down the internal components and prevent overheating. Fanless computers use alternative cooling methods and lower-powered components that give off less heat. As a result, these machines are quieter during operation, use less energy and are often more compact than fan-based computers. These advantages are particularly important in business settings.
