Why should a driveshaft maintain flexibility while continuously transferring torque between powertrain components?

A) drivetrain components change angles in relation to each other during operation
B) must continuously change length as drive axles react to torque and road changes
C) driveshafts expand and contract with temperature changes
D) all of the above

Driveshaft Flexibility

The ability of a driveshaft to flex or bend without breaking, to accommodate movement and alignment changes in a vehicle's drivetrain.

Powertrain Components

Parts of a vehicle's system that produce power and deliver it to the road surface, including the engine, transmission, driveshafts, differentials, and final drive.

Drivetrain Components

The collective parts of a vehicle's drivetrain system, including the engine, transmission, driveshafts, differentials, and axles, responsible for propelling the vehicle.
