Which of the following settings is controlled by jumpers?

The correct answer is D. Drive hierarchy. Physical jumpers on IDE (PATA) hard drives and optical drives were used to set the drive's role as Master, Slave, or Cable Select - establishing the drive hierarchy on an IDE channel.

Explanation

Physical jumpers on IDE (PATA) hard drives and optical drives were used to set the drive's role as Master, Slave, or Cable Select - establishing the drive hierarchy on an IDE channel. Chassis detection threshold, fan speed, and USB voltage are all software/firmware-level settings managed through the BIOS/UEFI, not physical jumpers. Jumpers are hardware bridges that set configuration states at a low, physical level and were most commonly associated with IDE drive configuration.
