Final answer:
The term 'torque converter' is used because it allows engine torque to be transferred in an automatic transmission.
Step-by-step explanation:
The term 'torque converter' is used because it allows engine torque to be transferred in an automatic transmission. Option C is the correct answer.
A torque converter is a fluid coupling device that is used to transmit power from the engine to the transmission in an automatic vehicle. It contains a turbine, impeller, and stator which work together to transfer and multiply torque. When the engine rotates, it generates torque which is converted into fluid flow within the torque converter. This fluid flow then transfers the torque to the transmission and allows the vehicle to operate smoothly.
