Given a class hierarchy where Piece has a method move() and King overrides it, what will happen when calling move() on a King instance?

AThe <code>Piece</code> class's <code>move()</code> method is executed

BThe <code>King</code> class's <code>move()</code> method is executed

CBoth <code>King</code> and <code>Piece</code> methods execute automatically

DA runtime error occurs due to method conflict

Step-by-Step Solution

Solution:

Step 1: Understand method overriding
When a subclass overrides a method, calling it on subclass instance uses the subclass version.
Step 2: Confirm behavior on King instance
Calling move() on King runs King's overridden method, not the base Piece method.
Final Answer:
The King class's move() method is executed -> Option B
Quick Check:
Overridden method call = subclass method [OK]

Quick Trick: Subclass method overrides base method when called [OK]
