Which of the following IEEE 802.11 standards operates natively in both the 2.4Ghz and 5Ghz spectrum?

The correct answer is D. 802.11n. 802.11n (Wi-Fi 4) introduced dual-band support, meaning it can operate on both 2.4 GHz and 5 GHz simultaneously. This gave it backward compatibility with older devices while offering higher speeds. By contrast: 802.11a is 5 GHz only, 802.11b is 2.4 GHz only, and 802.11g is 2.4…
