Forms of Inheritance:

Single Inheritance: It is the inheritance hierarchy wherein one derived class inherits from one base class.

Multiple Inheritance: It is the inheritance hierarchy wherein one derived class inherits from multiple base class (es).

Hierarchical Inheritance: It is the inheritance hierarchy wherein multiple sub classes inherits from one base class.

Multilevel Inheritance: It is the inheritance hierarchy wherein subclass acts as a base class for other classes.

Hybrid Inheritance: The inheritance hierarchy that reflects any legal combination of other four types of inheritance.

As far as visibility is concerned: Here it is.

Visibility Mode: It is the keyword that controls the visibility and availability of inherited base class members in the derived class. It can be either private or protected or public.

Private Inheritance: It is the inheritance facilitated by private visibility mode. In private inheritance, the protected and public members of base class become private members of the derived class.

Public Inheritance: It is the inheritance facilitated by public visibility mode. In public inheritance, the protected members of base class become protected members of the derived class and public members of the base class become public members of derived class. ;.

Protected Inheritance: It is the inheritance facilitated by protected visibility mode. In protected inheritance, the protected and public members of base class become protected members of the derived class.

I think the right answer would be option D.

Multilevel inheritance?

Multiple inheritance?

As it is derived from two classes public x, public y this is known as multiple inheritance.

Dude its derived from class A so it probably must be Multilevel or Hierarchical Inheritance.

It is syntax of multiple inheritance.

It consist of two base classes members that's why it is multiple inheritance.

Which inheritance is the combination of other two inheritance?

Hybrid or Hierarchical?

Please explain me.

Java doesn't have multiple inheritance. It has to be implemented with interface and that does not seem like the interface definition and declaration.
