Why each option
Of the listed options, WPA provides the strongest encryption and authentication for wireless networks, making it the most secure choice.
Disabling SSID broadcast is a security-through-obscurity measure that does not encrypt traffic; the SSID is still detectable by network scanners and provides no real protection.
WEP (Wired Equivalent Privacy) uses a static RC4 key that can be cracked in minutes using freely available tools, making it considered cryptographically broken.
Using static IP addresses on a wireless network provides no encryption or authentication and is not a wireless security mechanism.
WPA (Wi-Fi Protected Access) uses TKIP encryption and improved authentication mechanisms that were designed to address the well-known vulnerabilities found in WEP. It provides substantially stronger protection of wireless data in transit than WEP's static RC4 keys, and later versions such as WPA2 and WPA3 use AES encryption for even stronger security. For the available options, WPA represents the greatest actual cryptographic security for the wireless network.
