C Sharp (C#) - Polymorphism and Abstract Classes

What does the virtual method dispatch mechanism in C# primarily allow?
virtual methods let child classes provide their own version of a method. What is the main benefit?

AIt forces the program to call the base class method only.

BIt makes all methods static by default.

CIt disables method overriding in child classes.

DIt allows the program to decide at runtime which method version to call.

Step-by-Step Solution

Solution:

Step 1: Understand virtual method purpose
Virtual methods allow child classes to override a method and provide their own implementation.
Step 2: Identify when method is chosen
The actual method called is decided at runtime, based on the object's real type, not the variable's type.
Final Answer:
It allows the program to decide at runtime which method version to call. -> Option D
Quick Check:
Virtual method dispatch = runtime method choice [OK]

Quick Trick: Virtual means runtime method choice, not compile-time [OK]

Common Mistakes:

MISTAKES

Thinking method is fixed at compile time
Confusing virtual with static methods
Assuming base method always runs
