In order to restrict a variable of a class from inheriting to subclass, how variable should be declared?OptionsPrivateProtectedPublicStatic

In order to restrict a variable of a class from inheriting to a subclass, the variable should be declared as "Private".

Here's why:

1. Private: The private access modifier is accessible only within the same class. So, if you declare a variable as private, it cannot be directly accessed from outside the class or by any subclass, hence restricting inheritance.

2. Protected: The protected access modifier is accessible within the same package and also from the subclass of other packages. So, if you declare a variable as protected, it can still be inherited by a subclass.

3. Public: The public access modifier is accessible everywhere. So, if you declare a variable as public, it can be accessed from any class and can be inherited by any subclass.

4. Static: The static keyword is not an access modifier, it's a non-access modifier. A static variable belongs to the class rather than the object. It can be accessed from any other class. But, it's not related to the concept of restricting inheritance.

So, the correct answer is "Private".

The variable should be declared as "Private". In object-oriented programming, a private variable is only accessible within the class that declares it. This means it cannot be accessed by subclasses or outside classes, effectively restricting it from being inherited by a subclass.
