Explanation

Option B is correct because 802.11n access points are backward compatible with older Wi-Fi standards, specifically 802.11a, 802.11b, and 802.11g. This means clients using those older standards can still associate with and connect to an 802.11n AP, not just clients that support 802.11n itself. Option A is wrong because it assumes the AP restricts connections exclusively to 802.11n clients, which misunderstands how the 802.11 standard family handles compatibility - the AP negotiates the connection at the highest mutually supported rate, falling back as needed. The 802.11n specification was explicitly designed to interoperate with legacy devices to ease enterprise migration.

Memory tip: Think of 802.11n (and later standards) as "speak down" technology - a newer AP can always talk to older clients by dropping down to a common protocol, so the AP's maximum capability never locks out legacy devices.
