LLD - Design — Chess Game

AThe move() method in Knight is not marked as override

BThe move() method has different parameters in Knight

CThe base class move() method is final

DThe Knight object is not instantiated

Step-by-Step Solution

Solution:

Step 1: Check method signature matching
For polymorphism, overridden method must have same name and parameters.
Step 2: Identify signature mismatch effect
If Knight's move() has different parameters, base method is called instead.
Final Answer:
The move() method has different parameters in Knight -> Option B
Quick Check:
Signature mismatch breaks override [OK]

Quick Trick: Override requires exact method signature [OK]

Common Mistakes:

Ignoring parameter differences
Assuming missing override keyword causes this
Confusing final with override
