Step 2: Identify solution
Adding a lock or synchronization ensures one write at a time, preserving all lines.
Final Answer:
Add a lock mechanism to serialize file writes -> Option D
Quick Check:
Prevent race conditions with locking [OK]

Quick Trick: Use locks to avoid concurrent file write conflicts [OK]

Common Mistakes:

Switching to Set-Content (still overwrites)
Removing -Append (loses data)
Writing to different files (not always practical)
