C Sharp (C#) - Properties and Encapsulation

Aset { if (value < 0 && value > 120) throw new ArgumentOutOfRangeException(); age = value; }

Bset { if (value <= 0 && value >= 120) throw new ArgumentOutOfRangeException(); age = value; }

Cset { if (value < 0 || value > 120) throw new ArgumentOutOfRangeException(); age = value; }

Dset { if (value > 0 || value < 120) throw new ArgumentOutOfRangeException(); age = value; }

Step-by-Step Solution

Solution:

Step 1: Understand the valid range condition
Age must be between 0 and 120 inclusive, so invalid if less than 0 or greater than 120.
Step 2: Check logical operators in conditions
set { if (value < 0 || value > 120) throw new ArgumentOutOfRangeException(); age = value; } uses '||' (or) correctly to check if value is outside the range.
Final Answer:
set { if (value < 0 || value > 120) throw new ArgumentOutOfRangeException(); age = value; } -> Option C
Quick Check:
Use '||' to check out-of-range values [OK]

Quick Trick: Use OR (||) to check if value is outside range [OK]
