The correct answer is C. HE (802.11ax). Explanation: 802.11ax, also known as Wi-Fi 6 or HE (High Efficiency), is the 802.11 physical layer (PHY) specification that supports operation across the 2.4 GHz, 5 GHz, and 6 GHz bands. This specification is designed to improve wireless network efficiency and performance, especially in environments with a high number of devices. 2.4 GHz and 5 GHz bands are already supported by earlier standards like 802.11n (HT) and 802.11ac (VHT), but 802.11ax (HE) extends support to the 6 GHz band as well, which was recently allocated for Wi-Fi use under Wi-Fi 6E.
