Answer - B - Wide SCSI has a bus width of 16 bits, whereas Fast SCSI has a bus width of 8 bits.

Key Takeaway: Wide SCSI has a data bus width of 16 bits and has a maximum cable length of 20 feet. It supports up to sixteen devices and has a bus speed of 5 MHz, along with a maximum transmission speed of 10 MBps. Fast SCSI has a data bus width of 8 bits and has a maximum cable length of 10 feet. It supports up to eight devices and has a bus speed of 10 MHz, along with a maximum transmission speed of 10 MBps (1 byte × 10 MHz = 10 MBps). Wide SCSI has a bus speed of 5 MHz while Fast SCSI has a bus speed of 10 MHz.
