Correct Answer - Option 4 : Backspace

The correct answer is Backspace.

  • The backspace key is used to delete a word or a line.
  • Backspace is the keyboard key that originally pushed the typewriter carriage one position backwards, and in modern computer systems moves the display cursor one position backwards.
  • It deletes the character at that position, and shifts back the text after that position by one position.

  • The Alt key on a computer keyboard is used to change (alternate) the function of other pressed keys.
  • Thus, the Alt key is a modifier key, used in a similar fashion to the Shift key. 
  • The shift key is a modifier key on a keyboard, used to type capital letters and another alternate "upper" characters. 
  • The Insert key insert (often abbreviated Ins) is a key commonly found on computer keyboards.
