Files older than 7 days have LastWriteTime less than current date minus 7 days.
Step 2: Match the correct syntax
Get-ChildItem | Where-Object { $_.LastWriteTime -lt (Get-Date).AddDays(-7) } correctly filters files with LastWriteTime less than (Get-Date).AddDays(-7).
Final Answer:
Get-ChildItem | Where-Object { $_.LastWriteTime -lt (Get-Date).AddDays(-7) } -> Option C

Older files filter = LastWriteTime -lt AddDays(-7) [OK]

Quick Trick: Use -lt with AddDays(-n) to find files older than n days [OK]
