Explanation

LEAP (Lightweight Extensible Authentication Protocol) is a Cisco-proprietary EAP method that authenticates wireless clients against a remote RADIUS server using a username and password exchange. It is the only option listed that involves a RADIUS backend. WPA2-PSK and WEP-PSK both use a locally configured pre-shared key with no RADIUS server involved. CCMP (Counter Mode with CBC-MAC Protocol) is an encryption/integrity protocol used by WPA2, not an authentication method. Note: Although LEAP has known vulnerabilities and WPA2-Enterprise (EAP-TLS/PEAP) is preferred in modern environments, LEAP is the only answer here that describes RADIUS-based wireless authentication.
