C Correct answer
Explanation

Traditional typewriters had Tab, Spacebar, and Backspace (or equivalent backspace mechanism), but did not have an Enter/Return key. Line breaks on typewriters were created by a carriage return lever, not a key. The Enter key is a computer keyboard addition for sending commands or confirming input.
