Suggested Answer: C

The use of symmetric, private keys in WEP encryption is associated with several weaknesses, one of which is that the keys often remain unchanged on networks for extended periods. This can lead to security vulnerabilities because if an attacker manages to compromise a key, they can potentially gain access to the network and decrypt data for as long as the key remains unchanged.

I think option C makes sense because WEP keys don't change often, which could be a security risk.
