B. Private, none (if no modifier is used), protected, and public.
C. None (if no modifier is used), private, protected, and public.
D. None (if no modifier is used), protected, private, and public.

Answer 1

The correct order of visibility modifiers in Java is private, none (if no modifier is used), protected, and public.

Step-by-step explanation:

The correct order of visibility modifiers for classes in object-oriented programming languages like Java is option B. Private, none (if no modifier is used), protected, and public.

The visibility modifiers in Java, which determine the accessibility of class members, are:

1. Private: Only accessible within the class where it is declared.
2. None: Also known as the default access modifier, accessible only within the same package.
3. Protected: Accessible within the same package and in subclasses of the class.
4. Public: Accessible from any class or package.

For example, if a class member has a private visibility modifier, it can only be accessed within the same class. If it has a protected visibility modifier, it can be accessed within the same package and in subclasses.
