In version control, the process of saving changes to a file or folder and unlocking the file or folder for editing purposes.

• A. Check Out
• B. Check In
• C. Database
• D. Constructor

Answer: (B)

Check-in is saving your edits back into the repository and releasing the lock so others can edit. In many systems with file locking, you first check out a file to begin editing, which places a lock to prevent conflicting changes. When you’re done, you check the file in, which writes your updates to the repository and unlocks the file for others to work on. In some environments the term commit is used instead of check-in, but the essential idea is the same: integrate your changes and release the lock. The other options don’t describe this workflow—checking out is the act of obtaining the file for editing (often placing a lock), while database and constructor aren’t related to version control operations.
