Which of the following is the MAXIMUM data transmission rate of 802.11a?

8Mbps is not a defined maximum rate for any standard 802.11 specification and does not correspond to 802.11a.

11Mbps is the maximum data rate for the 802.11b standard, which operates in the 2.4GHz band, not 802.11a.

802.11a uses OFDM (Orthogonal Frequency Division Multiplexing) modulation in the 5GHz frequency band to achieve a maximum theoretical throughput of 54Mbps. It was released alongside 802.11b but operates in a different frequency band, which reduces interference from devices such as microwaves and cordless phones. This 54Mbps rate is also shared by 802.11g, which operates in the 2.4GHz band.

107Mbps is not a standard rate; 802.11n introduced higher rates through channel bonding and MIMO, but 802.11a predates those enhancements.
