Suggested answer: B

Explanation:

The 802.11b standard is a wireless networking protocol that operates in the 2.4GHz frequency band and supports a maximum data rate of 11Mbps.It uses a 20MHz channel width and a direct-sequence spread spectrum (DSSS) modulation technique2.The 802.11b standard was released in 1999 and is backward compatible with the original 802.11 standard3. The other standards do not match the specifications given by the customer. 802.11ac operates in the 5GHz band and supports higher data rates up to 6.9Gbps. 802.11g also operates in the 2.4GHz band but supports data rates up to 54Mbps. 802.11n can operate in both 2.4GHz and 5GHz bands and supports data rates up to 600Mbps.It also uses a wider channel width of 40MHz and a multiple-input multiple-output (MIMO) technology3.
