Zigbee is the specification used in which IEEE standard?

Explanation:
Zigbee is built on the IEEE 802.15.4 standard, which defines the low-power physical and MAC layers for short-range wireless personal-area networks. Zigbee adds the higher layers—network, security, and application—to run atop 802.15.4, enabling mesh and other topologies for inexpensive, low-power devices commonly used in IoT and home automation. The other standards correspond to different technologies: 802.11 is Wi‑Fi, 802.16 is WiMAX, and 802.15.1 is Bluetooth.
