Explanation

Wireless media suffers from latency and jitter (B) because radio signals face interference, congestion, and variable transmission paths, causing inconsistent delays - a significant problem for real-time applications like VoIP or video. Packet loss (C) is also worse wirelessly due to signal degradation, obstacles, and interference causing data to be dropped and requiring retransmission.

The distractors are all reversed: wireless has lower security (not higher, A), slower data transmission (not faster, D), and typically higher costs for infrastructure (not lower, E) - making A, D, and E describe advantages of wired, not drawbacks of wireless.

Memory tip: Think of wireless as the "unreliable shortcut" - it's convenient but introduces the BaC problems: Bad timing (jitter/latency) and Crashed packets (packet loss), while trading away the security and speed benefits of physical cables.
