Which of the following allows 802.11n higher transfer speeds than the previous wireless standards?
The correct answer is C. MIMO technology. 802.11n introduced MIMO (Multiple Input, Multiple Output) technology, which uses multiple antennas at both the transmitter and receiver simultaneously. This allows multiple independent data streams to be sent and received at the same time through spatial multiplexing…

Explanation
802.11n introduced MIMO (Multiple Input, Multiple Output) technology, which uses multiple antennas at both the transmitter and receiver simultaneously. This allows multiple independent data streams to be sent and received at the same time through spatial multiplexing, dramatically increasing throughput. Previous standards like 802.11a/b/g used a single antenna path (SISO). While 802.11n also supports dual-band operation (option A), that feature alone does not increase speed on a single band. Enhanced encryption (option B) and backwards compatibility (option D) are unrelated to raw throughput gains.
