Why each option
802.11n is the only legacy wireless standard capable of operating on both the 2.4 GHz and 5 GHz frequency bands (dual-band).
802.11a operates exclusively in the 5 GHz band and cannot use the 2.4 GHz spectrum.
802.11b operates exclusively in the 2.4 GHz band and cannot use the 5 GHz spectrum.
802.11g operates exclusively in the 2.4 GHz band and cannot use the 5 GHz spectrum.
802.11n (Wi-Fi 4) introduced dual-band capability, allowing devices and access points to operate on either the 2.4 GHz or 5 GHz spectrum. This makes it the only standard among the listed options that can use both bands, offering flexibility in interference avoidance and throughput.
