MIMO technology in the 802.11n standard provides for which of the following benefits?
The correct answer is C. Multipath support. MIMO (Multiple Input Multiple Output) in 802.11n uses multiple antennas to exploit multipath signal propagation, turning reflected signals into useful data streams rather than interference.

Why each option
MIMO (Multiple Input Multiple Output) in 802.11n uses multiple antennas to exploit multipath signal propagation, turning reflected signals into useful data streams rather than interference.
Channel expansion is not a recognized benefit of MIMO; 802.11n channel expansion refers to channel bonding, which is a separate feature.
802.11n achieves a theoretical maximum of approximately 600 Mbps, not gigabit - gigabit wireless was introduced with 802.11ac (Wi-Fi 5).
MIMO uses multiple transmit and receive antennas to leverage multipath propagation - signals that arrive via different reflected paths are processed independently and combined, which increases throughput and reliability. This is the defining technical benefit that MIMO specifically introduces.
Channel bonding, which combines two 20 MHz channels into a 40 MHz channel, is a separate 802.11n feature distinct from MIMO technology.
