Which of the following is a true statement about the TOGAF Technical Reference Model?

The TOGAF Technical Reference Model (TRM) is a foundational model of generic platform services. It serves as a model and a taxonomy for a service-oriented architecture. The TOGAF standard explicitly describes the TRM as consisting of two main components: a taxonomy that defines terminology and provides a coherent description of the components, and an associated graphical model that visually represents the taxonomy of services. This structure helps in standardizing the technology portfolio and promoting interoperability.

A. TOGAF is a framework, not a rigid process; it recommends and provides tools like the TRM but does not mandate their use.
B. The TRM is a useful model within the TOGAF library, but it is not an integral or required part of the ADM itself.
C. The TRM is a generic model intended to be adapted and tailored to the specific needs of an organization.
E. The TRM and the Zachman Framework are different models with different purposes; there is no direct one-to-one mapping between them.
