Which module do all other modules depend on?

• A. Foundation module
• B. Foundation Framework
• C. Implementation Support Module
• D. Security and Privacy Module

Answer: (A)

The essential idea here is that there is a single base module that provides the common building blocks all other modules rely on. In this structure, the Foundation module defines the core data types, base resource structure, and common conventions used across the entire specification. Because every other module—whether it introduces implementation support resources or security/privacy considerations—builds on those fundamental definitions, they all depend on the Foundation module. The term Foundation Framework isn’t the official naming for this base, and while the other two modules cover important domains, they don’t serve as the universal base that all modules require. So, the module that all other modules depend on is the Foundation module.
