This answer is based on the definition of Statement of Architecture Work in the TOGAF Standard, Version 9.2 - Phase A: Architecture Vision 3, which states that “The Statement of Architecture Work is a document that may form the basis of a contractual agreement between the supplier and consumer of architecture services. It defines what will be delivered by an architecture project, how it will be delivered, when it will be delivered, and how much it will cost.” The Statement of Architecture Work is an input to Phase B, as it provides the scope, approach, constraints, assumptions, risks, and deliverables of the architecture project. The other options are not correct, as they are not documents that may form the basis of a contractual agreement between the supplier and consumer of architecture services.
