D.
WPA2-Enterprise
Suggested answer: C

Explanation:

WPA3-Personal is a simple, secure solution for a small business with a single access point. It uses a new security protocol called Simultaneous Authentication of Equals (SAE), which replaces the Pre-Shared Key (PSK) exchange with a more secure way to do initial key exchange. SAE also provides forward secrecy, which means that even if the password is compromised, the attacker cannot decrypt past or future data. WPA3-Personal also uses AES-128 in CCM mode as the minimum encryption algorithm, which is resistant to offline password attacks. WPA3-Personal requires low administrative overhead and supports a single SSID with no guest access. Verified
