In object-oriented programming, when all the methods of one class are
passed on to a subclass, this is called:

A.
Delegation

B.
Inheritance

C.
Multiple Inheritance

D.
Forward chaining

Explanation:
In inheritance, all the methods of one class, called a superclass, are
inherited by a subclass. Thus, all messages understood by the
superclass are understood by the subclass. In other words, the
subclass inherits the behavior of the superclass.
*Answer Forward chaining is a distracter and describes data-driven reasoning used in expert
systems.
*Multiple inheritancedescribes the situation where
a subclass inherits the behavior of multiple superclasses.
*Answer delegation, is an alternative to inheritance in an object-oriented
system. With delegation, if an object does not have a method to
satisfy a request it has received, it can delegate the request to
another object.
