Correct answer: B
Concept
An ISO reference number uniquely identifies a published standard; neighboring numbers may cover unrelated subjects. To identify a markup-language standard, match the full standard title with its official catalogue number.
Application
The official ISO catalogue names ISO 8879:1986 as Information processing — Text and office systems — Standard Generalized Markup Language (SGML). The W3C HTML 2.0 specification likewise describes HTML as an application of ISO 8879:1986.
Contrast
ISO 8878 concerns the use of X.25 for the OSI connection-mode network service.
ISO 8879 identifies Standard Generalized Markup Language (SGML).
ISO/IEC 8880 concerns protocol combinations for the OSI network service.
ISO/IEC 8881 concerns use of the X.25 packet-level protocol in local area networks.
Cross-check
Both the standard setter's catalogue entry and the HTML specification independently point to the same identifier. Therefore, the required standard is ISO 8879.
