Why each option
IEEE 802.11b operates in the 2.4 GHz band and has a defined maximum throughput of 11 Mbps.
The 802.11b standard, ratified in 1999, specifies a maximum physical layer data rate of 11 Mbps using DSSS (Direct Sequence Spread Spectrum) modulation in the 2.4 GHz band. This is a foundational specification of the standard and a commonly tested networking fact.
20 Mbps is not a defined maximum for any 802.11 standard and does not correspond to 802.11b.
28 Mbps is not a recognized maximum data rate for any IEEE 802.11 standard.
54 Mbps is the maximum data rate for 802.11a and 802.11g, not 802.11b.
