          Explanation
          

            
The stty command changes terminal settings. 'stty intr ^c' sets the interrupt character to Control-c. Option B uses 'stty intr ^c' (escaping the caret) which achieves the same result in a shell context. Option A uses 'tty' which prints terminal info, and 'echoe' controls erasure.
