C Correct answer
Explanation

Static encryption keys make networks insecure because they never change, giving attackers unlimited time to crack them through cryptanalysis. Encryption (option A) actually makes networks MORE secure by protecting data in transit. Network interface cards (option B) are simply hardware components for network connectivity, not security features.
