b) Constructor chaining
c) Inheritance
d) Encapsulation

Answer 1

The concept illustrated in this question is Constructor chaining.

Step-by-step explanation:

The concept illustrated in this question is Constructor chaining. Constructor chaining is a concept in object-oriented programming where constructors of a class call other constructors within the same class. This allows for the reusability and initialization of common code.

In the given example, the message 'Employee constructed' is produced when an object of the 'Employee' class is created. This constructor then calls the constructor of the 'CommissionEmployee' class, which results in the message 'CommissionEmployee constructed'.

This chain of constructors being called is a clear example of how constructor chaining works.
