Phrase: TLS extensions | Statement: [RFC 6066, defines, TLS extensions]

Target entity: TLS extensions
Context triple: [RFC 6066, defines, TLS extensions]

• A. TLS
  TLS (Transport Layer Security) is a cryptographic protocol that secures data transmitted over networks by providing encryption, authentication, and integrity between communicating applications.
• B. TLS
  TLS is the IATA airport code for Toulouse-Blagnac Airport, the main international airport serving Toulouse in southwestern France.

• E. TLS heartbeat extension (later deprecated)
  The TLS heartbeat extension was a Transport Layer Security protocol feature designed to keep secure connections alive and test reachability, later becoming widely known for the critical Heartbleed vulnerability that led to its deprecation.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
