Which of the following is a standard IEEE 1394 transmission speed?
The correct answer is B. 400Mbps. IEEE 1394 (FireWire) defines standard transmission speeds of 100, 200, and 400 Mbps, with 400Mbps being the most widely recognized standard speed for FireWire 400.

Why each option
IEEE 1394 (FireWire) defines standard transmission speeds of 100, 200, and 400 Mbps, with 400Mbps being the most widely recognized standard speed for FireWire 400.
While 100Mbps (S100) is technically a valid IEEE 1394 speed, the exam targets 400Mbps as the primary standard speed associated with FireWire 400.
IEEE 1394 (FireWire) specifies S100 (100Mbps), S200 (200Mbps), and S400 (400Mbps) as its standard transmission speeds per the original 1394-1995 specification. 400Mbps, known as FireWire 400, is the most commonly cited and tested standard speed for IEEE 1394. It is distinct from USB and Ethernet standards and represents the peak speed of the original FireWire specification.
480Mbps is the Hi-Speed transfer rate defined by the USB 2.0 specification, not IEEE 1394.
1000Mbps (1Gbps) is the transfer rate for Gigabit Ethernet (IEEE 802.3ab), not IEEE 1394.
