Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: RFC 821 | Statement: [SMTP, originallyDefinedIn, RFC 821]

• B. RFC 791
  RFC 791 is the foundational Internet standard that specifies the design, structure, and operation of the Internet Protocol version 4 (IPv4).
• C. RFC 792
  RFC 792 is the Internet standard document that specifies the Internet Control Message Protocol (ICMP), which is used for network diagnostics and error reporting in IP networks.
• D. RFC 1035
  RFC 1035 is an Internet standards document that defines the implementation details, message formats, and operational procedures for the Domain Name System (DNS).
• E. RFC 826
  RFC 826 is the Internet standard document that specifies the Address Resolution Protocol (ARP), which maps IP addresses to physical hardware addresses on local networks.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"
