PowerShell - Working with Objects

You run this code:

$list1 = 'apple', 'banana', 'cherry'
$list2 = 'banana', 'cherry', 'date'
Compare-Object $list1 $list2 -IncludeEqual

But you get an error. What is the likely cause?

AMissing parameter names -ReferenceObject and -DifferenceObject

BThe -IncludeEqual parameter is not valid for Compare-Object

CThe arrays contain strings, which Compare-Object cannot handle

DThe syntax is correct; error is from elsewhere

Step-by-Step Solution

Solution:

Step 1: Check parameter usage
Compare-Object requires named parameters -ReferenceObject and -DifferenceObject when using switches like -IncludeEqual.
Step 2: Verify syntax validity
Positional arguments do not bind correctly with -IncludeEqual; missing parameter names cause error.
Final Answer:
Missing parameter names -ReferenceObject and -DifferenceObject -> Option A
Quick Check:
Named parameters required with -IncludeEqual [OK]

Quick Trick: Use named parameters with -IncludeEqual to avoid errors [OK]

Common Mistakes:

Thinking named parameters are not required with switches
Believing -IncludeEqual is invalid
Assuming strings cannot be compared
