Answer: A) It is directly accessible only in B1
Explanation: In the given chunk of code, Class B1 is a base class. Class B2 is derived class of class B1. Class B3 is derived class of B2. As you can see class B1 has two members or instance variables i and j. Instance variable cannot be directly accessible by both B2 and B3. If you see this statement of the given code private int j; the keyword private is used with the variable j. This keyword is called access specifier. Access specifiers specifies how the members of a class can be accessed. These members are attributes and methods of that class. Any member of a class that are declared private cannot be inherited by derived classes of that class. Additionally these private members cannot be accessed from within any method inside derived class. So j is directly accessible only in B1. You can access a private instance variable from within the same class or can access it through the methods of class.

Explanation: Networking technology is the term used to describe the entire processes through which computer or mobile systems are linked up either through optic fibers,wireless systems in order to enhance effective communication across networks or regions.
OSI (open system interconnection), the earliest models partitions into seven layers and the OSI is known as model that creates partitioning a communication system classing them into abstraction layers.
