Which of the following is described by the TOGAF Architecture Content Framework as a type of artifact that shows relationships between things?

A Building Block is a reusable component of architecture or solutions, not an artifact type for showing relationships.

A Catalog is a list of architectural elements (e.g., application catalog, data catalog), not an artifact type for showing relationships.

A Diagram is a visual representation of architectural elements, but a matrix is a specific type of diagram or table explicitly designed for showing relationships in a structured way.

In the TOGAF Architecture Content Framework, a Matrix is specifically defined as an artifact used to show relationships between various architectural components, such as a business-to-data entity relationship matrix or an application-to-technology matrix. Matrices are powerful tools for illustrating dependencies and associations systematically.

A Deliverable is a work product that is contractually specified and reviewed, which might contain matrices, diagrams, or catalogs, but is not itself a type of artifact for showing relationships.
