C Sharp (C#) - Polymorphism and Abstract Classes

What does runtime polymorphism in C# allow you to do?

ACreate multiple instances of the same class

BChange variable types at runtime

CCall derived class methods through a base class reference

DUse static methods without creating objects

Step-by-Step Solution

Solution:

Step 1: Understand runtime polymorphism concept
Runtime polymorphism allows a base class reference to call methods overridden in derived classes.
Step 2: Identify correct behavior
This means the actual method called depends on the object's real type, not the reference type.
Final Answer:
Call derived class methods through a base class reference -> Option C
Quick Check:
Runtime polymorphism = base ref calls derived method [OK]

Quick Trick: Think: base class ref calls derived method at runtime [OK]
