C Sharp (C#) - Properties and Encapsulation

You want to create a property Score that only allows values between 0 and 100. Which is the best way to implement the set accessor?

AUse <code>set { score = 100; }</code> always

BUse <code>set { score = value; }</code> without checks

CUse <code>get { return score; }</code> only, no set

DUse <code>set { if(value >= 0 && value <= 100) score = value; }</code>

Step-by-Step Solution

Solution:

Step 1: Understand validation in set accessor
To restrict values, add a condition inside set to check the value range.
Step 2: Choose correct conditional assignment
Use set { if(value >= 0 && value <= 100) score = value; } uses an if statement to assign only valid values between 0 and 100.
Final Answer:
Use set { if(value >= 0 && value <= 100) score = value; } -> Option D
Quick Check:
Validate values inside set accessor [OK]
