C Sharp (C#) - Polymorphism and Abstract Classes

Why is polymorphism important for code maintenance?

AIt makes code run faster by avoiding method calls

BIt forces rewriting all classes when a change is needed

CIt prevents using interfaces in the program

DIt allows changing code in one place to affect many classes

Step-by-Step Solution

Solution:

Step 1: Understand maintenance benefit of polymorphism
Polymorphism lets you change behavior in a base class or interface and affect all derived classes.
Step 2: Identify how this helps maintenance
This reduces the need to change many places, making code easier to maintain.
Final Answer:
It allows changing code in one place to affect many classes -> Option D
Quick Check:
