Several keys on a keyboard perform editing actions rather than inserting a new character, and each has a distinct, specific role during text entry.
The backspace key removes the character immediately to the left of the cursor each time it is pressed, which is the standard way to delete text while typing. The arrow keys only move the cursor position without removing anything, the enter key starts a new line or confirms an action, and the escape key cancels an operation or closes a dialog rather than deleting characters.
Because deleting typed text specifically requires removing characters one at a time from where the cursor sits, only the backspace key performs that function among the options given.
Exam takeaway: separate keys that move the cursor, like the arrow keys, from keys that remove content, like backspace, since students often confuse navigation keys with editing keys.
