Which section range within the Site and Infrastructure Subgroup is reserved?

• A. 30-35
• B. 36-39
• C. 15-19
• D. 02-14

Answer: (B)

Within the Site and Infrastructure Subgroup, certain section numbers are kept blank on purpose as reserved space for future use. This keeps the numbering flexible and stable so updates or additions can be added later without renumbering existing content. The range identified as reserved is simply that placeholder area, not currently used for any standard topic. That’s why it’s the correct choice: it represents the reserved block within the subgroup. The other ranges are used for actual, existing site and infrastructure topics, so they aren’t reserved.
