Final answer:
Option C. WPA2 is the most secure protocol for wireless networks due to its use of AES encryption, whereas WEP is the least secure. WPA is better than WEP but still not as secure as WPA2, and BitLocker is not a wireless protocol.
Step-by-step explanation:
Among the options listed for secure wireless network protocols, WPA2 (Wi-Fi Protected Access 2) is considered the most secure. WPA2 uses the Advanced Encryption Standard (AES), providing robust security.
In comparison, WEP (Wired Equivalent Privacy) is the oldest and least secure, as it can be easily compromised. WPA (Wi-Fi Protected Access) was an improvement over WEP but still falls short of the security provided by WPA2. As for BitLocker, it is not a wireless protocol; rather, it is a disk encryption program included with certain versions of Microsoft Windows, aimed at protecting data on hard drives. Therefore, it is not applicable to the security of wireless networks.
