Which of the following is a valid Boolean expression in PowerShell?
Atrue == false
B$true = $false
C$true -eq $false
DTrue = False
Step-by-Step Solution
Solution:

  1. Step 1: Understand PowerShell Boolean comparison syntax

    PowerShell uses '-eq' to compare values, not '=' or '==' which are invalid for comparison.

  2. Step 2: Evaluate each option

    $true -eq $false uses '$true -eq $false' which is valid and returns False. Options B, C, and D use invalid syntax for comparison.

  3. Final Answer:

    $true -eq $false -> Option C

  4. Quick Check:

    Boolean comparison uses '-eq' = A [OK]
Quick Trick: Use '-eq' for equality checks in PowerShell [OK]
Common Mistakes:
  • Using '=' instead of '-eq' for comparison
  • Using '==' which is not valid in PowerShell
  • Confusing assignment with comparison
