What part of the Architecture Repository shows the building blocks that are currently in use within the organization?

The Architecture Landscape represents an architectural view of the assets within an organization at specific points in time, typically showing the current baseline and future target architectures, and thus details the building blocks currently implemented or planned.

The Architecture Metamodel describes the organizational structure of the Architecture Repository and the types of artifacts it contains, not the actual building blocks in use.

The Governance Log records architectural decisions, compliance assessments, and project statuses, but does not directly show the operational building blocks.

The Reference Library provides templates, patterns, and reference architectures, offering guidance rather than a live inventory of deployed building blocks.

The Standards Information Base contains standards to which new architectures must conform, but it doesn't list the specific building blocks already implemented.
