Why each option
For 802.11ac in the US, the maximum channel width that can be achieved by bonding two subchannels is 160 MHz, which allows for higher data throughput.
802.11ac supports several channel widths, including 20, 40, 80, and 160 MHz. A 160 MHz channel can be formed by bonding two 80 MHz channels, which represents the maximum width specified by the standard and permitted under US regulations for such configurations.
120 MHz is not a standard channel width defined by the 802.11ac specification.
84 MHz is not a standard channel width defined by the 802.11ac specification.
240 MHz is not a standard channel width defined by the 802.11ac specification; the maximum is 160 MHz.
