A Correct answer
Explanation

SCSI-1 (Small Computer System Interface, first version 1986) supports up to 8 devices on a single SCSI cable. This includes the SCSI controller/host adapter itself, leaving 7 device IDs for actual peripherals. The devices are connected in a daisy-chain configuration. SCSI-2 and later versions maintained this limit for narrow (8-bit) buses, while wide (16-bit) SCSI increased it to 16 devices. SCSI-3 Ultra Wide also supported 16 devices.
