In the object-oriented design of a Snake and Ladder game, which component is primarily responsible for managing the state transitions of a player's position after a dice roll?

AThe Dice class, since it generates the number that determines movement

BThe Player class, as it holds the current position and updates it directly

CThe Board class, because it contains the snakes and ladders and applies their effects

DThe GameController class, which orchestrates the game flow and updates player positions accordingly

Step-by-Step Solution

Step 1: Understand the role of Dice
The Dice only generates a random number; it does not manage state transitions.
Step 2: Consider Player class responsibilities
Player holds position but should not decide how to update it considering snakes or ladders.
Step 3: Analyze Board class role
Board knows snakes and ladders but does not manage player state transitions directly.
Step 4: Role of GameController
GameController coordinates dice roll, queries Board for snakes/ladders, and updates Player position accordingly.
Final Answer:
Option D -> Option D
Quick Check:
GameController centralizes state transitions, ensuring separation of concerns.

Quick Trick: GameController orchestrates state changes, not Dice or Player alone [OK]

Common Mistakes:

MISTAKES

Thinking Dice manages player position
Assuming Player updates position without Board's input
Believing Board directly changes player state

Trap Explanation:

PITFALL

Dice and Player seem related to movement, but only GameController coordinates the full transition considering snakes/ladders.
