Explanation
Option C is correct because the four main database domains are System, User, Global, and Log - each representing a distinct scope of data management: system-level metadata, user-created data, globally shared variables/settings, and transaction/audit logging.
Why the distractors are wrong:
- A replaces "System" and "Log" with Local and VPN - VPN is a networking concept with no role in database domain classification.
- B swaps "User" for Event - while event scheduling exists in some databases, it is not one of the four core domains.
- D replaces "Global" and "Log" with Host and Network - these are infrastructure/network terms, not database domain categories.
Memory tip: Use the acronym SUGL - "Some Users Get Logged" - to remember System, User, Global, Log in order.
