Answer:
C. Draw band
Read Explanation:
The connecting device between the mainspring and the carriage in a typewriter is the drawband (also commonly referred to as the draw cord or draw tape).
Connection: One end of the drawband is attached to the mainspring barrel (or mainspring wheel), and the other end is hooked to the carriage frame (usually on the right-hand side).
Function: As the mainspring stays under tension, it pulls the drawband, which continuously exerts force on the carriage to move it step-by-step from right to left as each character key or space bar is pressed and released by the escapement mechanism.
