Why each option
WPA (Wi-Fi Protected Access) introduced TKIP and MIC as improved encryption and integrity protocols over the weaker WEP standard.
802.1X is an authentication framework, not an encryption method itself, and while WPA can use 802.1X, it's not the unique feature of WPA in terms of encryption, which is TKIP/MIC.
Preshared key (PSK) is an authentication method often used with WPA/WPA2-Personal, but it is not an encryption feature itself; TKIP/MIC is the encryption component.
WPA uses Temporal Key Integrity Protocol (TKIP) for encryption and Message Integrity Code (MIC) to ensure data integrity, which were significant improvements over WEP's RC4 and CRC-32 for enhanced security. These protocols are specifically designed to address the vulnerabilities found in WEP without requiring new hardware.
"Small Wi-Fi application" is not a technical feature of the WPA security standard.
