Why each option

Web-only mode SSL VPN is a clientless solution that requires only a compatible web browser with sufficient cryptographic capabilities.

AWeb-only mode supports SSL version 3 only.

Web-only mode SSL VPN supports modern TLS versions, not just the outdated and insecure SSL version 3.

BA Fortinet-supplied plug-in is required on the web client to use web-only mode SSL VPN.

Web-only mode is clientless, meaning it does not require a Fortinet-supplied plug-in on the client device.

CWeb-only mode requires the user to have a web browser that supports 64-bit cipher length.Correct

Web-only mode SSL VPN leverages the web browser's capabilities, requiring a browser that supports adequate cipher lengths to establish a secure SSL/TLS connection.
