Within the context of Enterprise Architecture, what are the layers that can be modeled with the ArchiMate language?

The ArchiMate Core Framework is structured into three distinct layers that represent different levels of abstraction within an enterprise. These core layers are the Business Layer, which models business processes, services, and organization; the Application Layer, which models software applications and their components; and the Technology Layer, which models the hardware and software infrastructure. This layered approach provides a clear and structured way to describe and analyze the relationships between business, IT systems, and underlying technology.

A. Strategy, Portfolio, and Segment: Strategy is an extension to the core framework, while Portfolio and Segment are concepts often used in TOGAF, not the core ArchiMate layers.
B. Data, Information, and Technology: Data and Information are aspects that exist within the layers (e.g., Business Object, Data Object), not the layers themselves.
D. Infrastructure, Operations, and Security: These are cross-cutting concerns or domains that can be modeled within the ArchiMate layers, but they do not constitute the layers themselves.
