PowerShell - String Operations

You want to create a file path string in PowerShell that includes a variable folder name. Which code correctly uses string interpolation to build the path?

$folder = "Documents"
$path = ?

A"C:/Users$folder/file.txt"

B'C:\Users\$folder\file.txt'

C"C:\Users\$folder\file.txt"

D'C:/Users/$folder/file.txt'

Step-by-Step Solution

Solution:

Step 1: Understand string interpolation and path separators
Double quotes allow $folder to be replaced by its value. PowerShell treats backslashes as literal characters in double-quoted strings and uses them for Windows paths.
Step 2: Check each option
"C:/Users$folder/file.txt": "C:/Users$folder/file.txt" interpolates but misses separator ("C:/UsersDocuments/file.txt"), invalid path.
'C:\Users\$folder\file.txt': 'C:\Users\$folder\file.txt' uses single quotes, no interpolation.
"C:\Users\$folder\file.txt": "C:\Users\$folder\file.txt" uses double quotes and proper Windows path syntax, interpolates to valid path.
'C:/Users/$folder/file.txt': uses single quotes, no interpolation.
Final Answer:
"C:\Users\$folder\file.txt" -> Option C
Quick Check:
Double quotes + Windows path backslashes + $variable = valid interpolated path [OK]

Quick Trick: Use double quotes and backslashes for Windows paths with variables [OK]

Common Mistakes:

Using single quotes which block interpolation
Missing path separators between directories and variables
Using forward slashes instead of backslashes
