Final answer:
In local area networks, Ethernet is the technology that uses the carrier sense multiple access with collision detection (CSMA/CD) protocol to manage data transmission and avoid data collisions.
Step-by-step explanation:
The carrier sense multiple access with collision detection (CSMA/CD) protocol is used in local area networks to monitor data traffic and avoid collisions when multiple devices attempt to send data simultaneously. Among the options provided, the correct choice that uses CSMA/CD is Ethernet. This protocol allows devices on the Ethernet network to detect if the communication medium is idle or being used by another device, and if a collision is detected, it instructs the devices to stop transmitting and try again after a random backoff period.
Other wireless technologies operate on different protocols. For example, Bluetooth allows for radio communication in the 2.4-GHz range for facilitating connections between nearby devices, like headphones and cell phones to hands-free devices. Unlike Ethernet, Bluetooth does not use CSMA/CD for collision detection.
