B$hash = @{ Name = 'John'; Age = 30 }

D$hash = (Name => 'John', Age => 30)
Step-by-Step Solution

    $hash = @{ Name = 'John'; Age = 30 } -> Option B

  4. Quick Check:

    Create hash table = @{ key = value; ... } [OK]
Quick Trick: Use @{} with key = value pairs separated by semicolons [OK]
Common Mistakes:
  • Using commas instead of semicolons
