Which statement about deleting lines of code is correct?

• A. Deleting a line requires only selecting it and pressing DELETE
• B. Deleting a line requires switching to the command line mode
• C. Deleting a line can be done without entering editing mode
• D. Deleting a line requires you to be on the address side in editing mode, highlight the line, press DELETE, then ENTER

Answer: (D)

In this editing environment, removing a line is an editing operation that requires a deliberate workflow. You must be on the line you want to delete (the address side) and in editing mode. Once the line is highlighted, pressing DELETE marks it for removal and you must press ENTER to confirm the deletion. This two-step process with a confirmation helps prevent accidental deletions and ensures the program is modified only after you explicitly confirm.

The other ideas don’t fit because simply selecting the line and pressing DELETE isn’t enough without confirmation, switching to command line mode isn’t how deletions are performed in this editor, and you can’t delete a line without being in editing mode since deletions are editing actions that modify the code.
