Apublic void Display() { }

Bpublic virtual void Display() { }

Cpublic new void Display() { }

Dpublic override void Display() { }

Step-by-Step Solution

Solution:

Step 1: Identify override syntax
To change a virtual method in a derived class, use override before the method signature.
Step 2: Eliminate other options
The plain public void Display() { } lacks the override keyword, public virtual void Display() { } incorrectly uses virtual in the derived class, and public new void Display() { } hides the base method but doesn't override it for polymorphism.
Final Answer:
public override void Display() { } -> Option D
Quick Check:
Override method uses override keyword [OK]

Quick Trick: Override methods must use override keyword [OK]
