Why each option
CDMA (Code Division Multiple Access) is the channel access technology used in cellular networks, allowing multiple users to share the same frequency band using unique codes.
Ethernet (IEEE 802.3) is a wired local area network technology used for connecting devices within a LAN, not for cellular wireless communications.
CDMA allows multiple users to simultaneously transmit on the same frequency band by assigning each call a unique spreading code, distinguishing signals through code separation rather than frequency or time division. It is the underlying technology for cellular standards such as cdmaOne and CDMA2000.
CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) is the media access control method used in wireless LAN (Wi-Fi / IEEE 802.11) networks, not cellular networks.
POTS (Plain Old Telephone Service) refers to the traditional analog landline telephone network, which is separate from and predates cellular network technology.
