C Correct answer
Explanation

CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) was developed specifically for wireless networks to overcome the media contention problem. In wireless environments, devices cannot detect collisions during transmission (hidden node problem), so CSMA/CA uses collision avoidance through random backoff timers and RTS/CTS mechanisms. It does not directly address bandwidth saturation, privacy, or device interoperability.
