C Sharp (C#) - Classes and Objects

You want to track how many times each Player object has scored points. Which design correctly uses instance fields to store this state?

class Player {
  public int scoreCount = 0;
  public void Score() {
    scoreCount++;
  }
}

What happens when you create two players and call Score() on each once?

ACompilation error due to missing static keyword

BEach player has its own scoreCount incremented to 1

CscoreCount resets to 0 after each call

DBoth players share one scoreCount incremented to 2

Step-by-Step Solution

Solution:

Step 1: Understand instance field behavior
scoreCount is an instance field, so each Player object has its own copy.
Step 2: Analyze method effect on objects
Calling Score() on each player increments their own scoreCount separately.
Final Answer:
Each player has its own scoreCount incremented to 1 -> Option B
Quick Check:
Instance fields track per-object state [OK]

Quick Trick: Instance fields keep separate data for each object [OK]
