B. RFC 7234
RFC 7234 is an IETF specification that defines HTTP/1.1 caching semantics, including how responses may be stored, reused, and validated by caches.
C. RFC 1441
RFC 1441 is an early standards-track document in the Simple Network Management Protocol (SNMP) framework that was later superseded by RFC 1901 as the protocol evolved.
D. MIME Sniffing Standard
The MIME Sniffing Standard is a web specification that defines how browsers should determine the media type of resources to improve interoperability and security on the web.
E. RFC 7233
RFC 7233 was an HTTP/1.1 specification that defined range requests and partial content delivery mechanisms for HTTP resources.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
